We recently upgraded to Accounts Receivable 8.1A and we're getting the following message when trying to access A/R:

Your current version of Accounts Receivable is not compatible with the version of Adagio Inventory database you are currently using.
The version of Adagio Inventory we're using is 8.0B

When we try to access Inventory we get the following message:

Old inventory data was found. Conversion from old versions is not supported.

We have 8 companies using Adagio and the problem is only with one of them.
