My wallet says transaction too large when I try to move around more.
This tends to happen if you use p2pool mining... Try setting up a new address and sending small chunks to that internally - say 10-20 FZ at a time...
This doesn't appear to be helping.
Please refer to the procedure described here:
http://frozencoin.org/forum/index.php?topic=221.0 ("Pool Miner's problem"). The general idea is to send all amounts of your accounts with small amounts via RPC command "sendfrom 200"
The best way is to have the in a new wallet.
