When Compacting and Repairing Databases the error: "Selected collating sequence not supported with the specified file format" occurs. I have compacted and repaired the two databases previously with no problem. This phenomenon has just begun to occur. One database is a conversion from 2000 but the other one is a fresh 2010 MDB.
The information I garnered so far has to do with upgrades of MDB's but none to 2010. Even then it does address the issue of the error occurring in a new 2010 database.
The databases are on a Win XP SP3 computer.
