When it boots up, do a Tools - New Config, and assign drives accordingly (you can also check off Parity is Already Valid)
With luck, everything will be back the exact same it was *. With no luck, reinstall CA, and see if Previous Apps has anything in it. If not, then install everything you want (your appdata will have survived all of this)
* If everything did come back the way that it was, go to the docker page and see what happens if you try to edit a container. If an error pops up something to the effect of "Was this created with this plugin", then you're ultimately at some point going to have to delete the docker.img file and reinstall all of your apps from scratch (although your appdata will be intact)
