Using CR 2013 with DB2

I am using Crystal Reports 2013 with IBM DB2 database. My computer is Windows 7 Pro 64 bit. The software is the trial version of CR 2013. Whenever I try to add more than one table to a query, I get a message "Crystal Reports has stopped working", and then it closes the program. I can create a report using one table and it works fine, but adding another table causes the crash.
