Hi, I just upgraded to Cubase 5 from Studio 5 and every time I launch reverence and now roomworks, a run time error is displayed and crashes the program. Why? Noah.
I have heard from other members that sometimes removing the preferences file helps “reset” default plugin versions. However before doing that, when you launch Cubase, try going to ~Devices/Plugin INformation and make sure you click the Update buttons “I just do both of them, because I’m not sure really which does which” 
Can you specify the CPU and memory on your system? Also, what OS you’re on and whether 32 or 64 bit.
