Hi Kpt. Munson, should be no problems but save your existing menu_1024_768.ini file first, check to see if the relevent Groups have the same title and if the blocks are the same, should be, if you use JSGME then you could install/uninstall with no probs, if you have any problems just PM me to arrange for you to email your menu_1024_768.ini file to me, I will edit for you & send back.
Cheers.
Reece.
