New Install of Win 8.1 - InnerSpace?

I've done a new install of Win 8.1. Can I still run InnerSpace (and ISBoxer) from the other disk where it's already installed, or do I need to do a new install of the ISBoxer install package? If so, do I have to remember my account credentials, or can I retrieve them from the previous install? (I can still boot into the old OS.)

Edit: Ok, here's how I did it. I reinstalled 'Lavish.ISBoxerBundle.exe' in the new OS (Win 8.1). In ISBoxer I renamed the default starter ISBoxerToolkitProfile.xml to ISBoxerToolkitProfile-20130925.xml and saved it off to the NAS. Then I went to the other disk where I was running Win Server 2012 and copied the ISBoxerToolkitProfile.xml to the new OS and then opened the InnerSpace/Scripts folder and copied all of the ISBoxer.ClickBars.*, ISBoxer.Menus.*, and ISBoxer.VideoFeeds.* files to the matching folder on the new OS. Voila!

The only thing left to do was to add WoW and dxNothing to the "Add Game" dialog in Inner Space and everything was running like it was on the previous installation.

i reinstalled windows 8 a few weeks ago, copying the innerspace directory wasnt as smooth as i expected

i just reinstalled the entire package, cleared up some weird issues.
