Feathercoin Wallet wont Unlock?

[MrMushroom]

Recently updated my Wallet Box only to find my FTC wallet wont UNLock.
No problems with my other coins added New Send and Receive address' to all no problems unlocking them.
The password IS correct.
Copied Contents of the Feathercoin Blockchain/Wallet directory and the Program Files directory to another computer.
Started it up Tried to add a receive address input the SAME password it worked.
Tried to add some more address' but its not accepting the password that just worked.
It's now  Permanently Locked on 2 computers
Now I just want back in so I can get my coins and get rid of it.
Any helpful suggestions appreciated.
