Problem: Windows frozen up after running Multicam software for a certain while.
There is a error message that shows applicaion hangs due to the Multicam in Event Viewer of Administrative tools in Control Panel.

Solution: It's because Video log storage is taking out all the space on C drive. It would happen when the C drive gets full. The solution to fix this problem is isolate the video storage on another HDD or partition. Go to system Configure and Set Location, then setup another path on other HDD or partition for Video Log Storage.
