Sorry, figured it out - initially I couldn't change my details as the registration form would not allow any entry - I am on Vista and as soon as I ran the Jabaco IDE as admin I was able to update my details OK.

Hi, I'm back after an absence. I re-installed Jabaco on my PC - no problem - but when I look at the info display in the IDE it shows my old email address (no longer in use) and my old registration. I suspect that when I removed Jabaco previously the registration file (which must be hidden away somewhere) was not deleted and the new install did not overwrite the previous values. How do I fix it?
