I'm starting to have problems with 2D Toolkit in a project that had been working previously. Basically, it keeps getting stuck on a progress bar that says "Scanning Project" and I end up having to Force Quit. For example, when I try to create a Sprite (ie. choose Sprite from the Assets Create menu) then it just goes to scanning project.
I have installed an updated version of Unity to test with, but I still kept the old version installed too. Specifically, this project was created in and I'm still opening it in Unity 4.2.2, but I recently installed Unity 4.5 in a different location. As part of that process we renamed the old Unity folder from "Unity" to "Unity42" perhaps that's related to this problem?
I realize I don't really have much information to go off of, so there's only a slim chance that this can really be solved, but I'm hoping to maybe get some pointers to troubleshooting steps to try. I did try the "Rebuild Index" option in the 2D Toolkit menu but that didn't fix it; anything else I should pay attention to?
