The resource startup order is wrong.
This line:
ERROR: account\login-panel\server.lua:2: exports: Call to non-running server resource (mysql)
Shows that 'mysql' needs to be started before 'account', so put 'mysql' above 'account' in mtaserver.conf
Check each ERROR line to fix the start order.
Something is changing the update file. Could be a virus, or even anti-virus doing something odd.
Solution is to download and run the installer from https://www.multitheftauto.com/
1) Uninstall NahimicMSI. (It has an OSD component which might be interfering with MTA)
2) Test MTA and see it fixes the problem
3) Install the latest from here maybe: https://www.facebook.com/nahimic/
4) Test MTA and see it fixes the problem
Looks like the 'account' resource needs other resources starting first
'mysql', 'global', 'pool'
Check the lines 'Call to non-running server resource' see what resources are missing
There is a problem with the stealth_pro resource.
We will need to see the complete mods\deathmatch\logs\server.log file
Upload it here: http://upload.mtasa.com/
Try renaming gta-sa.exe to gta_sa.exe
If that doesn't help, reinstall the steam version and run the MTA:SA installer from http://www.multitheftauto.com
(The installer should automatically downgrade the steam version (as long as it hasn't been modified))
