.tkc tutorials

Hello, back from the mountains and digging in. I thought I should start a new thread because the topic has changed quite a bit from original. I have looked at the tutorials link on the main page and down loaded the first ten along with the tKC Tutorial Viewer 2000 v3.1. The viewer executed ok but the preferences for tut folder could not be reset. Setup defaulted to the root folder and I cannot change it. If anybody can help I would really appreciate it.

Thanks in advance,
d
