VC 6.0 and Crystal Reports 4.5...help plz...!

Hi Guyz...
I have an hard job, got to interface a VC 6.0 code to an old CR 4.5...
Does any1 know if it is possible...?
I am doing it, but it seems CR does not want to read the Right Database when setting the appropriate 'DataFiles' path.
If I use the CR stored dataFile, the report appears to me and updates with database updating...
if I set a different 'DataFile', it always shows me a blank page ( reportviewer )...
but no any error from CR...just a blank page...
of course the 'location' is the report is settled as 'same as report'...

tnx for any advice...

:wave:
