Hi to Foxcoin community (my first post on forum also).
I did have the same problem with wallet as TorVek. I also downloaded version 1.6 to the new computer (like any new user would) and I got the same problem. The wallet didn't synchonized (forgot on which block it stalled). Maybe someone else can check this out on his own and then confirm/denial it here. If this is the case, we got major problem, because new users are unable to participate.
Then I deleted all files except wallet file (do not forget to BACKUP WALLET before), downloaded version 1.5.3, run the foxcoin-qt and it started to synchonize

. My goal was to pass problematic block, so I closed program immediately, run 1.6 version and all worked fine. Now I can send/receive coins like before.
Be carefull when running qt version 1.5.3 for too long, you probably risk creating a fork and funds in your wallet will be lost.
