Time & Billings 9.2A (171024) error messages when trying to post invoices

- unable to open data file billing text @B92ABLT, (1213)
- unable to open data file billing tax @B92ABLX, (1213)
- unable to open data file billing subline temporary @B92ABLS, (1213)


Not able to get out of error messages, so used task manager, I then get these messages,
- access violation at address 0040944E in module TimeBilling.exe. Read of address 00000192
- Internal error: (2103) application handle invalid

Time & Billings shuts down and when I reopen the batch is gone.

Data integrity check does not show any errors in time & billings or in receivables.
