Hi mattj,

Try this ways (step by step):
1. disable all modules in moi/ui/customui/ directory. run MoI.
2. disable moi/ui/customui/CustomInit.js (just rename it). run MoI
3. restore original /ui/CommandBar.htm, erase moi/ui/customui, moi/objects, moi/snapshots directories. wait for more information. :)
