As far as I can see it doesn't have anything to do with this mod.
It clearly says something about:
com.teamcos.modularsystems.storage.containers.ContainerModularStorage

If it is a mod pack, please contact the mod pack creator before issuing here.

Note: that doesn't mean I won't look at it anyway, but it doesn't seem to be my fault so far.
