I've been downloading some movies for some time from torrent sites. Just yesterday, I couldn't launch them at all. My JetAudio says there's been an error. My WMPlayer gets illegal instruction. Just by mere visiting the folder on thumbnail preview Windows give out an error message that prompts it to close. Now even my previously working movies don't work anymore. I transferred one of the movies and played it from my friend's laptop it worked fine.
But some movies I took from my cam stored in other folders worked fine.
I followed the 11 steps. System Restore Off. Run SuperSpyware, CCleaner, SpyBot, etc in safe mode. But the error's just the same. Sometimes I would get Dr.Watson Postmortem Debugger.
