lmule and xmule trouble

Suddenly lmule stopped working (or xmule). Somehow files is the ~/.lmule/ can get easily corrupted. Just remove all the files (or even delete the whole directory) and the program works again. Don't forget to save the files from the Temp and Incoming directories! You can copy them later back into the newly created ~/.lmule/Temp and ~/.lmule/Incoming directories.
