Matching CATraxx version to Access database

[Rick Coffman]

I have used an old version of CATraxx for years but have retired the system it ran on.  I upgraded the CATraxx database from an unremembered version of Access through Access 2007 and into Access 2010 using the Access built-in upgrade process, and I have the Access db files for both versions.  The database opens OK in Access and I can query tables.

Access files:

OURCDS.MDB           (unknown Access version)            
OurCDs2007.accdb    (upgraded to Access 2007)
OurCDs2010.accdb    (upgraded to Access 2010)
  

The current verison of CATraxx gets an error trying to open the databases

i have the following saved install vesions of CATraxx:

7                    10/21/2015
8-20
8
9-31
9-32
9-33
9-34
9-35
9-41
9-44_Final
9-47_Final
9-48
9-52
9-55

Can someone advise on how I can get my CATraxx database back in sync to the CATraxx vesions?  I assume that along the way the CATRaxx installs must have made database design modifications that are missing in my database version.  I insrtalled v9.55 and it errors out trying to open my database.

Is there anything short of installing each old vesion in succession and try to open my database?

This is a tough one.
CATraxx will only open MDB files.
Ver 9 should open it and prompt to upgrade if needed. How ever if you have made changes to the database structure, more than likely it will fail.
If you can get the files back to Access 2002-2003 that may help too.
