Ubuntu server 14.04.1 32bit.
Compiled and running with no errors.
Command line client shows correct balance and transaction history.
GUI wallet shows correct balance, but no transaction history.
At the lock screen, a message about a mandatory upgrade is appearing.
At the accounts section, the message "This account is not voting with some of its stake..." appears above all accounts with balance in them.
I tried rescan to recover the transactions in the gui, but nothing changed.
