Crystal Reports XI - failed to compile

We purchased Crystal Report Nov 2007 and had no problem opening a report that was extracted from an accounting database. We are in the process of upgrading this person to a new machine. We installed Crystal and tried to open the report but we get this error "The saved data will be discarded since one or more formulas failed to compile." We have uninstalled and reinstalled and we get the same thing. We checked to see if the versions were different and they are not there both running Crystal XI version 11.0.0.1282 on Windows XP SP2. We have changed machines and we get the same thing yet we go to other machine with the same specs and we have no problems so we don't know what to try next. Can you help? Jill
