Hi,

This morning when I tried to run protoshares-qt.exe I got the message "Error loading block database. Do you want to rebuild the block?". IRCC protosjares-qt was properly closed last time I used it.

Here is the debug.log:

Questions:
1) what does this "ERROR: CheckProofOfWork() : hash doesn't match nBits" mean? Which can be the causes?
2) Is save to "rebuild the block"? Which are the consequences?
3) If "rebuild the block" is not the way to go, what do you recomend me to do?
4) Last one, are my PTS save?

Thanks in advance.
