Alan very recently published a blog post about de-installing v5 and running the Cleanup tool if one was having problems. I am having problems and would like to try this. That said, I have v4.12 still installed because it still works for some of the issues I have had. The questions I have, does running the Cleanup tool damage or cause issues with v4.12? Is the tool self explanatory? I don't believe I've actually seen a set of instructions for the tool.
