Can anyone help me out?

I have trouble claiming my CLAMS. I have a fully synced Clam client, and my wallet.dats. I'm using File -> Import Wallet, select my BTC/LTC/DOGE wallet.dat -> enter the password. But nothing seems to happen after that.

Am I doing something wrong?

Also, the just-dice chat box tells me my addresses have unclaimed CLAMS.

Edit: just found that my console tells me this:
"19:34:54  CDB : Error 2, can't open database (code -1)"
