Have a problem with your GTA or SA-MP and NOT LVCNR? Post here.
Well, i'm having some issues with this. If i exit out of the interior, sometimes it freezes and i have to open a task manager and have to end task on GTA:SA. Maybe this could be only a GTA prob.
UPDATE: Sometimes happens when it's loading SAMP screen on, it just crashes
I remember having problems exactly like those (i use win 8.1 too) but I forgot how I got it fixed, try searching youtube
