Crystal Report error Ucrpe32.Pas missing

When I step thru my code I get
Unable to locate source file, Ucrpe32.pas Ignore this file.
I say Ignore and it continues .
It is having a problem when I set the ReportName at Run Time.
cpre1 := RptDir+RptName+'.rpt';
When I look at the Value in RptName it is ok until I get the above error
message.  Then After that my RptName is non Existant.
Error occurs on line of code( with crpe1 do)
This was working fine before I upgraded to 6.0 although I think I had the
ucrpe32.pas for 5.0??  And now I don't for 6.0.  Why is it looking for the
source anyway.
Please Help.
