Ok, I figured it out, I have to make a new certificate and provioning file with the generated certSigningRequestcsr file from the 2nd pc.
Will b4i stil be working Ion the 1st pc, Because the certificate and the provisioning files are made with another certSigningRequest.cer, which was the problem on the 2nd pc, so I'm afraid I have to make a new cert. and prov. file evrytime I switch from pc.
