WTF! I upgrade from MVPI to MVPI2, sync fine with existing credits, as trial I purchase 2 credits and apply to my own car.. System works. Had to buy 2 more credits for L98 today and paid for credits, came out of my paypal account, shows as extra credits in total purchased credits but wont sync ?. So I purchased two more credits and same again, my a pain in the fuckn arse!!! lost a customer and down 4 credits ?.. FUK!!!!!!
