The title says it all. I've been using Pluraleyes to sync hours of footage and when I try to frameserve with Debugmode I get the error: Unable to create signpost AVI file. Please close any applications that may be using this file and try again.

I'm thinking the culprit is Pluraleyes (other projects that I haven't used Pluraleyes on are unaffected by this error), but how exactly do I close it? I'm using Sony Vegas 9 Pro 64-bit. I don't see anything relevant under task manager processes that has the name "Pluraleyes" in it.

Or is there another way to get Debugmode to work without closing Pluraleyes? Would be a bummer if I had to create a Lagarith file just to send to my encoder. Hours saved from Pluraleyes would then be wasted on creating an intermediate file and I would like to avoid that.
