mirv_camimport_load problem

So I've been testing Smoofofer a bit, and keep running into this problem. Everything works fine until the part where I need to import the new .bhv file with mirv_camimport_load "F:/smooth.bhv". Console just says "Error", nothing else. I've also tried with "F:\smooth.bhv" and the file does exist in my F drive.
Sadly it won't even work with the unmodified .bhv file.

"Note: Recording needs to be started at least once before the import works."
Tested, didn't help.

Any ideas?

..fuck. thanks haha
