Product Re-registration Problem

OK - so I have been using Bitdefender for quite some time now and generally I have very few problems with it apart from some niggles with Network settings. Anyhoo thats not my problem.


My old licence had 47 days left to run, as installed on 3 PC's in the house.


I normally purchase a new licence within ample time as normally it simply adds on the remaining licence to the new licence.


This is in fact the case for 2 x PC's which now display 412 days remaining.....however my PC for some reason has simply reset back to 365 days on the new licence. Why?


Im baffled, and a little annoyed as now Im going to have 3 PC's out of sync with their licencing!


Any advice please?
