Built a new machine with Windows 7 Ultimate 64 bit. I had Windows 7 Pro previously. It crashes every time after opening cdr. Re-installed multiple times. NO joy.. please help

I have reinstalled the program multiple times now.. Every single time I open up a CDR it may open or it may just crash then. Or open for a second or two then crash..  I have tried running under the recomended shell.. such as XP sv pack 2...    Which is strange because it ran for years on my Win7 Pro 32 bit wit no issues..   I do have to let use different fonts as I don't have them all loaded on the new machine yet.  font issue?   CDR's without fonts seem to open and run a bit longer until crashing..  I sure appreciate your help;   I need it to work so bad..   thank you
