Thanks Craig,

I found them, deleted all, even executed VFPClean.APP, but still crashing!
I noticed that strange things happens after the form is released, even coding a lot in the "destroy" of the form: CRViewer.ReportSource = NULL, releasing the objects oReport and oCrystal, and ThisForm.ReleaseObject("CRViewer") ... nothing works - if the form is called again in sequence, VFP crashes.
It seems like something that refers to the Crystal components are not beeing released. A simple USE ? or a DO FORM ? from the command window also does not open the dialog, the cursor just moves to the next line and nothing happens.

I have VFP8 and VFP7 in the same box, and everything works fine in VFP7.
Should I remove VFP8 and reinstall from scratch ?

I have not even thinked about those FoxUser files, and can´t even remember where they are ... I´m on the way to try to find them :)
