This morning i had to reload GSAK on this lappy, Max by any other name ! lol, anyway i downloaded the latest and greatest gsak 7 (thinking now, doh that 8 might have been worth a try) getting to registration i could not find the serial, bugger i said and then emailed Clyde with a fresh request for my serial, that job done, next...... before i had time for next i had a return mail with the info
that is what i call service to the customer, Clyde you are a gem 
so the moral is thanx heaps Clyde for the service your product i cannot recommend any higher, thanx again.
GSAK has become a major part of our caching travels and without it would be nearly like going back to paper and a garmin 12, shudder ,shudder
