"Error Opening Block Database"

[s4l1h]

Client is very buggy.

You can remove all data files and after open client.

Close client.

go C://Users/YourUserName/appdata/Rooaming/memorycoin/

save and backup wallet.dat file(or copy and save all files) and remove other files re-open client.

++ download latest version memorycoin wallet

when I start the latest version of memorycoin, it pops this error message

"Error opening block database.
Do you want to rebuild the block database now?"
with the option OK or Abort

When I click OK, it opens a new window that says "error opening block database" and crashes

I'm running Bitcoin QT, what gives?  Same thing happened with the original Memorycoin client.  Running windows 7
