Hi
Can you start your wallet with the following commandline arguments:
-rescan -zapwallettxes=2 -debug
Let me know if this helps, if not please open an issue on
https://github.com/ROIcoin/ROIcoin/issues and provide me the
debug.log that command generated ( will be in same directory as your wallet.dat file ).
