Manycam crashes when connecting to certain Amcrest cameras


I recently installed ManyCam to try it out. Was very impressed with it.

I have been able to use ManyCam with various IP cameras including (Samsung SNH-P6410BN) flawlessly. However, when I connect to Amcrest IP4M-1051W, the program immediately crashes.

I connect using the following URL:
[configure userid/password]

The crash is so bad, that when I try to re-open the program, it immediately dies again when it attempts to reconnect.

Are there any logs or information that can provide insight on why it wont work with these cameras? Thanks
