It is not at all unusual for users to register successfully and participate in a forum of this nature for a long interval only to find themselves suddenly unable to log in and / or perform basic standard operations.
This can be from several causes, but by far the most common is some problem with the cookie file on the user’s system.
Fortunately, this is an easy do-it-yourself fix!
Shut down all applications, leaving yourself at the desktop.
Start your browser . . . for the purposes of discussion, this will be presumed to be Internet Explorer . . . the tasks are the same for Firefox, Opera, etc., but the menu locations and titles will be different.
Click on “Tools” . . . then “Internet Options” from the consequent menu.
A smaller window will open with several tabs at the top.
Select the “General” tab. Under that look for “Browsing history” and click the “Delete” box.
This will present you with a list of five types of files / data which may be removed. You can select these individually or choose the “Delete all” box at the bottom. [color=blue]CAUTION:[/color] Deleting “all” will remove many auto-completion options you may have chosen. This does not cause a system failure, but it will mean you must manually re-enter the information removed when you next visit a given site or use a given feature within a site. For your purposes here, deleting the first three types: files, cookies and history, does the job.
cCleaner is a fast and effective FREE utility which will do all this for you and you can download it here: http://www.ccleaner.com/ . . . note that one of the big advantages of the application is its broad applicability - it will do IE, Firefox and Opera all at once, so if you use multiple browsers, you do not have to repeat the process. It also is much faster to use than drilling down through multiple menus with the browsers.
OK, so the clutter is gone.
Now, just to be sure the problem isn’t related to spyware (the second most likely cause of such problems), run whatever anti-spyware applications you prefer. If you do not have such applications already, you truly [u]need[/u] them! Not that these are not already bad due to privacy concerns, but many, more malicious, bits of code can piggy-back on the spyware and infect your system with virus, worm and hijack code.
[color=blue]Adaware[/color] is regarded as a decent FREE application: http://www.lavasoftusa.com
[color=blue]Windows Defender[/color] is also FREE and while it is labeled a “Beta” (unfinished product) it performs very well at this time - this and the cost are not normal features of Microsoft products, so no promises on how long either will hold true (NOTE: this application functions under Windows XP only!!): http://www.microsoft.com/downloads/details.aspx?FamilyId=435BFCE7-DA2B-4A6A-AFA4-F7F14E605A0D&displaylang=en
[color=blue]Spyware Doctor[/color] is NOT free, but is consistently rated highly: http://www.pctools.com/spyware-doctor/download/
Of course, there are many other stand-alone products available and various utility suites such as Symantec or McAfee include anti-spyware applications in the package, as well.
So, clutter is gone, spyware (if any) has been trashed.
Shut down the computer.
If you have a separate, stand-alone modem and / or router, unplug it / them and wait thirty seconds or more.
Re-start the computer.
Once the computer has finished booting, plug in the modem. When it has warmed up, plug in the router.
This sequence will almost always fix the problem.
