Red nodes on Mouse and Keyboard

Hey all

Trying some small patches in VVVV and i’m always getting red nodes inside the Camera (SoftImage) node. Specifically Keyboard and Mouse are both red.

It started happening a few days ago, I could probably chase down exactly what it is. But does anybody have any experience with this? / hints as to causes

Thanks!
Elliot

fixed it by disabling a plugin i was developing
perhaps a .net version conflict
