Error code 132 'Letters'

OK here is the problem:

We are running Maximizer Enterprise 5.5 (Btrieve version 07.51N) with Pervasive SQL 2000 and our database has reached 4GB. Now our users are receiving a “Data Manager has returned an error code of 132”, with a message of “An unidentified error has occurred on the 'Letters’ file.'

I searched the KB on Maximizers site and got the following message.

Btrieve file has reached the maximum allowable size of 4 GB.

Maximizer only supports running on the Btrieve "0600" (Btrieve 6.x) file format and therefore is limited to a file size limit of 4 GB. Currently, the supported solution is to use Maximizer’s purge feature. To purge your documents, select Purge > Document from the Maximizer File menu.

The Development department understands that the 4 GB limit may be inconvenient for some customers. Converting from Btrieve 6.x to 7.x might seem like a simple solution, but the Development department first wants to ensure the Btrieve 7.x version is fully tested before Maximizer users are converted.

Maximizer Enterprise 7.0 will provide a SQL Server version that will support larger file
sizes.

However I am not running Btrieve 6.x I am running Btrieve 7.51N and since we use our notes and attached documents the idea of purging them is out of the question.

Boy do I need some help!

Thanks
