Help please. Silo uvmap going crazy


today silo uv mapping has gone crazy it now has a wide blue band around the uv map and it cannot be textured, selected, using vertexes, lines or faces, in fact you cannot work with the uv mapping.

I have tried reinstalling but it still is happening. it did not start until today.


Finally figured out how to fix it. somehow the preference file became corrupt and even when reinstalling it used the same preference fileā€¦ so copied it from 2.5 installation and it worked
