Since 2 days I have issues syncing my wallet.

A few days ago I installed v0.9.2.0 and it didn't sync, then I added "enforcecheckpoint=false" to my maxcoin.conf file, which fixed the problem. But now, since 2 days, my wallet is not syncing any more. The last confirmed transaction I have received is from 3-9-2014 08:11, after that I have one unconfirmed transaction and then nothing... It is stuck at block 593393 of 598947.
