Groups Module 1.0.0 (Dolphin 7.0.0): Tried, tested and failed. The original 1.0.0 is a mess. Although Groups works fine however it is not multiple-module-friendly. Hence, improvement in 1.0.1. If you try changing 1.0.1 to 1.0.0 and 7.0.1 to 7.0.0, chances are... it will not work because the scripts are different. If you refused to update to 7.0.1, then you're out of luck. I will try to maintain in later versions (7.02, 7.1, etc).
