So unfortunately I ran into a problem upgrading from version 1.92 final. I followed all the steps, my integrity checked out. After I restart unity though, its almost like 2dtoolkit uninstalled itself. When i click on the 2dtoolkit toolbar, the only options are advanced and setup for JS. In the hierarchy and project panels there is no more 2dToolkit options at all. I have spent all day on this but to no avail. I am using Unity version 4.1.5f1. Does anyone have any idea as to why this is happening?
