It sounds like you're trying to run script on a non-powershell thread, probably via an async callback. This is not a supported scenario. The trick is to "bridge" to callback to the eventing infrastructure, where scriptblocks haev a default runspace. Take a look at what I wrote here:

It shows you how to work with async threads in powershell and run script in response to callbacks.
