I've deleted the modules and downloaded them from your link. I stopped allmodules and only activate the BPM Global 3.3 and Layer Sequencer 2.1.
I use M8 2.6.4 on a MacBook Pro Intel Core 2 Duo 2,16 GHz, 3GB Ram, ATY RadeonX1600 with 128 MB VRam with Mac OS X 10.6.8
When I start the Layer Sequencer there are some Errors.
