hey all
I tried to play SA:MP after installing Windows 7. Everything was going properly until I downgraded GTA SA. Everytime I try to connect to server, this message shows up

I've got an original CD, but I haven't got another CD/DVD drive to test. I haven't got problems like that on my last system -XP,
what should I do?

EDIT
Single Player isnt working also...
