Rob, I'm glad that connecting to the BTRIEVE engine through the Data Explorer got you going on Crystal again...it can be slower as, Lorne pointed out, if the files you are using are large...but speed is not always necessary depending on how often you run the report.  ODBC is a nice option and it sounds like you need to get it working.  If I hear of anything that might be helpful I'll check back in with you.
 
Take care..
