Whenever I try to set up the LiveSplit plugin on OBS it keeps crashing the program. I'm just trying to have it so I can split whilst in the middle of a run. I hate to keep tabbing out every time a split is reached. Plz help :D

Don't use the OBS plugin. It's unstable and to my knowledge has never been fixed or improved. However, you can enable Global Hotkeys, so you don't have to alt-tab everytime you want to split.
