Hello Cristina, > In the attach you can find the trace of the registration.
I have checked your tracefile and confirm: that is a problem which needs further debugging. Up to now I did not activate "WITH_REGINFO" in my installation, therefore I cannot compare. If I find time (this weekend) I will do that and come back with the findings.
