tested new win client. crashes all the time.
when you shut it off, it downloads whole chain AGAIN from start.
losing my interest.
and no sync without addnodes.
Delete from %appdata%\Bitcredit folders "bidtracker" and "database".
After it will start without any problems if you have the correct chain. If not, start the wallet with -reindex.
The hardcoded nodes are unavailable. Till then, I don't think that is a problem if you add by hand some nodes ...
