Blacksite Area 51 "no DVD" issue
 

I have been trying to "UnRAR" and "UnZIP" the vty-0122.7z file and the .NFO appears at the extraction folder but not the .EXE it just won't unpack. Winzip says its "not a valid archive" I've re downloaded it 4 times and always to a new folder. If I use WinRAR, then after the .NFO file appears the progress window for the .EXE file to extract just sits at 0%. It will just "hang" and then I have to shut it down manually. Everything else I have in .ZIP or .RAR form inflates 100%.

Do you use latest version of WinZip and WinRar?
Try to use 7zip: http://www.7-zip.org/

You might just have had to read the PC Games forum FAQ; there's an entry for exactly such problems...
