Help needed please. Wallet problem.

My Bulwark 1.3.1.0 wallet worked fine until my PC froze yesterday. Since than when i try to open the wallet the icon shows up in the tool/task bar and that's it.
When i right click on the icon in the tool bar i get some options like send/receive/repair/whatever but no working interface.

Steps so far tried to solve this issue:

- Deleted all Bulwark folders
- Deleted all Bulwark Reg files
- Restart and new Wallet install with new downloaded wallet files.
result: no success

- renamed folders
result: no success

- tried to use a backup i had when updating from 1.3.1 from 1.3.0
result: error message: Failed reading from database. pcoins tip from database is incorrect .....

- used only wallet.dat from back up.
result: no success

Nothing helps. Same issue over and over again. Any ideas, suggestion, advice? whatever?

Thx in advance.
