Bank Manager error

SUGGESTED

After closing the year-end I cannot use Bank Manager. I receive these two errors:

1. A Column ID occurred more than once in the specification.

2. Error 567 (Provider v. 5.6.8.0): Column does not exist: .....

I found possible solutions here and I tried them.

I tried to open Bank Manager in the Demo company. Bank Manager issued the same error in the Demo company, so both my company and the Demo company cannot utilise Bank Manager.

It however worked in a third company that I tried.

I then followed further steps and deleted the Statementdata.sdf file  to see if that would work. I could not find any LETxxx files. None of this solved the problem and i still cannot use Bank Manager.

Any solutions please?
