Hi I cannot find the override directory, so I can remove the experience cap, and have tried locating an override file with no luck. I have seen a previous answer which says the directory resides in the root of your BG2 installation. Please tell me how I can find this. Thank you

Right. Normally, the BGII folder will install under your program files directory. Then there is a subdirectory called Black Isles. Then you have BGII-SoA or something close to that (depending on your install). After that, you should see the override directory there. Check it out and put the file there. Party on!!!!!!
