Awhile ago I had a problem of not being able to move enough redpower 2 frames with a frame motor and that was easily fixed by changing linksize in the redpower 2 config file. But, I lately updated my mod pack and the config file was reset which wouldn't be a problem except when I change the linksize from 1000 to 9000 minecraft crashes on start up and even if I go back to the config files and reset linksize to 1000 it still crashes on start up and I have to delete the config file and run minecraft again.
