Failed to Connect to Database

[KirianHeffentrager]

Hello All,

I recently tried to add data with an .xlsx extension and the following error occurred:

Failed to connect to database. An underlying database error occurred. Class not registered.

I saved the file under the .xls extension and it worked. I am running the dinosaur 9.3 version but have never had a problem with it handling files in windows 7 before. Why am I suddenly getting this error when trying to bring .xlsx files into the program?

Thanks, Kirian
