Novice needs advice

[ChipW]

Hello. I inherited a database of several thousand records that are used for a tour. However, whenever I try a search or sort of the current database it keeps asking me to open or find an older version of itself. Since that old file was in the same folder I inherited with the new one, I do open it and then it works fine. I'm wondering, however, why this is happening and if there is some change I can make to the current database to stop it. Hope I explained this well enough for someone to understand. Thanks in advance for your advice!
