I downloaded last (trial) WinZip version, and uncompressed my files, without errors this time! Thx so much.
But now i have another question: i clicked setup.exe and installed the game, but when i start it, it begins to update the files: is this necessary, once i have downloaded full C4 client from web-site?
And if this is necessary, how long will it take?
im wondering about the update files as well, because after the first update finishes downloading, i get an error that says "Compression failed. Check hard disk space." Then it disconnects me from the update server. I have plenty of hard drive space, so wtf?
