I had a issue when I first wanted to get into gta sa again on my new computer. I transfered my game from my Mac I put windows on. Needless to say it didn't work at all. It would crash, and samp couldn't find servers. I then Uninstalled everything, and restarted my PC, then reinstalled. Same issues. I kept doing this, trying different downloads, making sure to wipe everything, and restart my PC everytime I repeated the process. Nothing worked. Tried plenty of mods and fixes, still nothing. This was a BRAND NEW gaming pc.
Wanna know what fixed it?
I unsintalled everything, said the fuck with samp, and didn't try again for months until the announcement of rcrp. I downloaded a clean gta, and samp again, everything worked as intended. My guess is, when I transfered it originally, something was sticking in my system from it, through all the new installs. I don't know how or where, but it fixed itself.
