CLS A310 Aircraft wont show up in selection lobby

I have just bought the CLS (commercial level Simulations Airbus A310 and A300 and I have Installed them manually to the CORRECT fsx Directory on my computer like I would with any other addon.
Only thing is When I go to start flight simulator and select my aircraft, it is not there to selectI have gone through the list one by one to find and its not there.... I have reinstalled this addon plenty of times and have also installed it on my laptop with the same problem. I tried to figure out what the proplem was by going through the Aircraft.cfg file and also going through the A300 Beluga from CLS which I got a fair time before hand (which did work perfectly) and found no differences in the aircraft.cfg file.
I am indeed very confused as to what has happened and how to fix it.... I am out of Ideas and as I payed for this Aircraft I would very much want to get it working.
I will include my computer specs if it helps
