Hi,
Since a lot of people seems to have problems with RageMP not updating or being corrupted, I decided to post those instructions for future reference.
This may help people, for my part, I didn't know that rage's process was in the background and it prevented me from updating without my knowledge.
I will update this with time if a better and/or more complete method exists.
STEPS TO FIX (would work for most update / corruption problems)
1- Make sure any 'ragemp*.exe' processes are closed, especially 'ragemp_v.exe' (also exit the 'updater.exe' process);
2- Verify your GTA5 files with steam or with the Social Club launcher;
3- Delete every files in your RageMP folder except the updater (if instructions doesn't work the first time, re-download updater.exe from the RageMP website);
4- Make sure GTA5's files have finished being verified and that RageMP's update is over;
5- Make sure you start RageMP with no arguments. For example: disable cef debugger;
6- Start the ragemp_v.exe and enjoy!;
If you need more information to "verify your GTA5 files", follow these instructions.
Thank you,
