Cant save new keyword shorcuts

I dont like the default TB basic keyboar setup…so I made mine…BUT…when I do something…or X RANDOM thing happens…ALL THE COMMANDS ARE CHANGED…dont work anymore…it either change XML file…or the hotkeys I changed NO longer work.
so frustrating…
so I have TO REDO ALL WHAT I DID…for what? for it to fail again…and start all over again…
its this a bug? how can I fix this??!!
