CrystalReport loading the original report after modification

Well, this may seem very very strange, I installed CR13SP5 today and after that I modified a report but when I excute. It loads me the original one !

I did verify the rpt source and it's pointing to the right version.

FYI: there're only two OrdreTransfert.rpt files on my pc, one in debug and another in the project folder.

Update : I found that MainReport Shows the good version but Main Report Preview is showing the original version ! Could that be an unexpected behavior ?

OTC.Load(String.Format(@"{0}\EtatsEdition\OrdreTransfert.rpt",Environment.CurrentDirectory));
