VST BRIDGE CONNECTION LOST

i tried loading up some old working tracks, now all of a sudden iam getting this error. i read around on the forums but iam still not sure what to do.

i think the problem is coming from my prophet and sub boom bass vst’s. if i buy this jbridge software, will these working files load up without any problems?

also will cubase6 have upgraded bridge software so we wont have these problems?

thanks
