I downloaded FaceRig yesterday. It worked initially, but after opening several times, it started to pop out "ASSERTION FAILED". If I press "continue", there will be another alert "UNFANDELED EXCEPTION INFORMATION", And whatever I click it just stop working or exit. I've checked what equipment is requested, no problem there.

Here's another problem. Sometimes FaceRig shows message :"ERROR, camera not available....", but I'm quite sure that there's no other apps or whatever using my camera. BTW, my camera is Iriun Webcam.
PLS HELP ME.
