In the Lightsaber Walkthrough of Achilles', somewhere in the beginning there's written I don't have to extract the mdl and mdx files, but double-click them, so the image viewer shows up. But the image viewer doesn't show up, when I doubl-click, there's a window opened, called Model Extraction Options. Then there are some options etc.

Is there something wrong?

You use the image viewer to look at the .tpc texture files. You extract the .mdl and .mdx files by using the extract button on the right hand side. Must be a typo.

Oh, k, thx.

Good luck with the project, btw ;)
And I expect an update the first of January (Not, of course :p)
