I just tried to install fresh clean copy of GTA:SA and so far I have no problems with it. Topic can be closed. Thanks for help and sorry for bothering.
Hold on, it now says I'm missing some files in /audio/streams, going to get all those files first.
EDIT: Okay, I got it working and finally generated the log: http://pastebin.mtasa.com/165140785
MTA still gives me the same error, but now it appears when I just launch it
Hello, there is a problem with my MTA.
Whenever I try to connect to any server (even to the local) the next error appears:
I tired to launch MTA with different options selected in the Optimus window (that appears on MTA start-up) but it didn't help.
For some reason I can't get MTADiag to work, it just diagnoses things for eternity and thus can't generate logs.
Please, help me solve my issue. Thanks.
