I try to save stuff on my laptop, but in the download manager for Firefox 3, executables cannot be run, videos cannot be played, and everything when right clicked, does not allow the option to open the file or open the file's folder. I tried in IE also and tried saving a .exe and running it from the source, neither worked. I restarted and still am having the same problems. I saved a random piece of a website just fine. I can save notepad files just fine too. The internet appears to be normal also.
Hmm, we need tech support here fast =/ I shall see if anyone i know that has knowledge with these things can help ya, in the meanwhile, you try your best to find ze problem.
