Earlier I used Sonart x3 in windows 7, Recently I switched to a new computer. and Started to use Sonar platinum  (SONAR PLATINUM, WINDOWS 10 ENTERPRISE, 32 GB RAM, Intel i7 - 5775C 3.30GHz - Edirol UA101) In my new system I cannot load "Virtual Bassist". When I load transporter freezes. Is there a reason for this or a way to solve this problem  ... Please Help

could be your soundcard not keeping up.
which it should no problem (the edirol)
check your latency settings, make sure your using ASIO as well.
some times when we switch to a new build, there are things we need to set up in preferences.

Thanks Chuck Jones  for your reply, I use the same sound card earlier - Enyone using " steinberg Virtual Bassist" in windows 10. 

and what im saying is when you move to a new system from sonar X3 windows 7 - to sonar platinum windows 10
there might need to be some setting that need to be redefined. this has happened to me before.
 
with that being said, im not sure virtual bassist is supported anymore so it might be a windows 10 issue.
I could only find MAC OSX binary on their website
