Robbo, honestly, this is not a Ketron support forum and whilst its fine to air your grievances, if you have a problem you realy do need to put the effort into chasing your distributor, after all they took your money to support you.
I know for a fact that if we have a problem similar yours at Ketron UK (and in all honestly it does happen from time to time) Ketron Italy work with us to resolve the problem. We can talk to them by phone and email. Some issues take a little longer if they are more challenging, but we have always been able to work them out.
I don't know about your particular problem (first I have heard of it) - but the factory do need to know so they can help, so please do contact your distributor.
Send your serial number and the checksum and alltabs test results as the factory are only going to ask for that information anyway.
