I also cannot cash out do to a locked wallet from an old wallet (ltc.kattare.com). Did you try from a different computer antipopxx? I Tried to contact burnside twice in the last couple weeks with no reply. Hopefully these will be resolved soon.

lol im in the same boat, had to register just so i can pm him about my locked wallet. Hopefully tomorrow i will be able to, and yes the 360sec timer is a bit frustrating.
