After installing Commerce license and all its dependencies, I am getting this fatal error along with these "WARNINGs"

Warning: class_implements(): Class CommerceLicenseEntityController does not exist and could not be loaded in entity_crud_get_info() (line 724 of /.../.../.../sites/all/modules/entity/entity.module).

Warning: in_array() expects parameter 2 to be array, boolean given in entity_crud_get_info() (line 724 of /.../.../.../sites/all/modules/entity/entity.module).

Someone please help!!
