Renamed. Ran the mintcoin-qt.exe directly from its folder. Got no wallet found, option to import was presented.
Program menu was running - stopped the synch attempt...
( I now recall that my PC crashed while mintcoin was runing -sorry forgot to mention that)
well, put your wallet.dat back in after closing it... the block chain got corrupted
Thanks for the quick help
Block chain finished loading day before yesterday, and new mining entries are accruing; but I see a message in the small window at the bottom of the UI that says the block chain checkpoint is too old. I ran repair wallet and it fixed an entry. I let it continue to run in hopes it would fix itself in a day or 2, but it has not.

I tried to use the open debug log file to provide the last entry here, but it will not open ( file in use by another process). If need those entries I can stop the process and snip a few.
Pls advise
Thanks
