VocATC 5.55 not showing ai with MyTraffic X 5.2

Hi, I am a new VoxATC user who has been happily flying around europe for the last 3 weeks with Voxatc 5.55 and MytrafficX 5.2 under windows XP. In order to get better performance and more Ram for add-Ons I have installed vista64 (which has made a big difference by the way).The problem I have is that no matter what I try, re-instaling, deleting, renaming, even re-installing FSX, I cannot get Voxatc to show traffic with mytraffic 5.2. My traffic works perfectly through FSX, but as soon as I turn fsx traffic to 0% and activate Voxatc, nothing. Voxatc is generating traffic but it is just usually 1 single learjet or similar even at EHAM etc. I have this problem at all airports including default and add-on. I have tried 5.55c.I have tried everything I could find on here relating to traffic but to no avail.Please help! I am becoming bored of flying alone and LOVE vox atc.FSX SP2 (DX9)Vista Ultimate x64 on Macpro 8 core4 GB RamNeil.
