Your pool is not paying out. It mines, but the coins are stuck in the pending balance.
Currently Fixing the problem. It should send the payments in a few minutes.
EDIT: Payment is being sent already. I pointed my miners a while ago so it can mine more blocks to offset the balance left on the old wallet. You should get your full balance in a few minutes up to an hour.
That wallet generator is not compatible with freelabit gui wallet, because gui wallet needs a private key and a .wallet file
Sorry, yes its currently not compatible. I just hope they update their wallet since its basically a fork of forknote and updated versions of forknote supports importing private keys.
