Cannot play movie clips or video files
 

BIG HELP NEEDED
Have just downloaded new version of Limewire it will not play most of my video files. Under Icons the symbol is for a Ciprex Video File instead of movie clip as it used to be. How did this happen and how can I change it? It doesn't matter what format the files are in MPEG 4 , MPG, AVI it is all the same

I Think You Mean "Cliprex Video File".
It's Very Possible that You Have Become Infected.
Run A Full System Scan With Your Antivirus Program. This Appears to Be Spyware so if you Have a Spyware Program, Run It Also. Spybot S&D is Free if you don't have one.
Hope this Helps.
