Same Errors:

Those error messages are fine its just the application telling you it cant show you the contents of xpr fonts at the moment. Once you have opened the skin like you have done, you should be able to expand the skin browser tree and view files held with in it.

i have the same errors with blackbolts skin.

i cannot get a preview and when i try to view images it crashes

same problem exactly... any ideas?

I have made some changes to the application and hopefully fixed the main bug of the preview image freezing. So hopefully you will have more luck with the application now. You can get the latest copy from the downloads page on main site.
