When you done the uninstallation, did you check that EVERYTHING was removed? 9 times out of 10 just running the uninstaller doesn't remove everything and in some cases it will leave some files behind (for when you reinstall) these would normally be the config files, you could try just remove that file from your Rising World folder / New version (just cut and paste) to the desktop and when you run the game again it will be like the first time you have run the game! and in the worst case that that still didn't help just paste the original file back again.
Now Im not saying that doing this will help, but in some games it can.
