21/05/2016 UPDATE: SOLVED!

Thank you guys!!! I updated my video card driver as suggested and now it works!!! Now everything works fine! As far as the new interface is concerned, Only one suggestion: please change menu character colors because in many case they are almost unreadable (i.e. grey on dark grey background and similar) or provide additional option to adjust their brightness....
Hi, just bought and installed V collection 5 but all instruments have the same issue: the interface is completely black, i.e. they instruments works fine (the midi keyboard play, and try clicking in the upper left corner bring the file menu on...only the panel window is completely black...no graphics, no button, no keys,....please help me!

Please be informed that I owned the previous V Collection 4 which is still running good (all panels are shown correctly...)
Thank you in advance!!!
(PS my system is windows 7 system 64 bit 4 core 4GB ram)
