Ow, Ow and OK

G'day,
I have had a few problems with locking up. I had to unlock twice, but at least the third time seems to be working. I have been locked for over half an hour now. The first lock up every time seems to hurt, and the second time I was just out of the shower (everything was hanging low). I'm not sure why I always have to take it off and put it back on half an hour after the first lock up. It is working now though.

Does anyone have any ideas as to why this happens?

Finally secured at 9:00am,
Cody
