Movie player classic etc disappeared

[nic]

Hi Mark and all,
I'm using V2.1 in license mode for V1 (will upgrade when the pay cheque comes in, though I don't need the new features yet).
All has been fine up until just now when I've discovered that the Movie Player, Video in Watcher and many of my video sources & renders have completely disappeared. When I open a patch which did have a Movie player in, it seems to red/brown out the respective actors which are not functioning. The only thing I can think of is that I mistakenly opened V1.3.1 by mistake (it's still in my dock), which may have moved these actors or something?
Any suggestions to help would be appreciated as I'm in the middle of production (as usual)
thanks,
Nic
