tracks keep jumping to start and end

Hello
I have a problem. Once i start a track it plays for a short time , then either returns to the start and stops or goes to the end of the track and stops. Also i signs pops up and states : VST system link has been deactivated because of too many receive errors !!.

I dont know if the two are connected , they maybe ?

its very frustrating as its one of my favourite tracks ! can anybody help me please,
would be much appreciated

thanks
