Hi D/C,

Does the error message start with 'Critical error 1212'? If so, then the problem is related to missing or incorrect dictionaries in the \softrak\dict directory. When posting in Adagio Invoices, this would require not only the correct Invoices dictionaries but also A/R and I/C, and Job cost if you use that. If anything is out of synch, this would result in the error you received.

That you have a clearing account number 1212 is likely coincidental.

When did you start receiving this error? Likely very recently.
Did you do any recent installations with Adagio or 3rd party applications that writes to the dictionary directory?
You mentioned the error occurs from one computer on the server. Are there other computers for which this works? And do they use the same network mapping as the one that gives the error?
