Hi guys  
I think I’m locked somewehere…I updated to 0.42b and I noticed it keeps updating at block 114972 (last block was 518 days ago)  
How to unlock this? I left it updating for 12 hours and nothing changed…  
Thanx

One way to solve this is to delete all files in ./ppcoin except wallet.dat and ppcoin.conf and restart.  
Peercoin has relatively a small blockchain to synchronise and that should not take long
