Hello. I am having trouble changing back to my default skin. I am using Dr. Nuke's Flex currently, and it was installed as a site admin. When I try to change it, I get a horrible error. -  please see thread http://www.dotnetnuke.com/Community/Forums/tabid/795/forumid/108/threadid/297232/scope/posts/Default.aspx

To recover the site from this error, I need to do a database restore and restart the server. However, I got tired of my hosting provider telling me that they can't keep restarting the server, so I tried to Preview the default MinimalExtropy skin. This didn't kill the site, but it only opens a new tab with my Flex skin. The resulting URL may provide a clue to why it won't even do a preview, and is similar to the site error message that cripples the whole site when I attempt to change to the default skin.

 http://XXXX.com/Default.aspx?tabid=37&error=Value+cannot+be+null.%0d%0aParameter+name:+type&content=0

I then noticed that MinimalExtropy was only available in the Host Setting, and not the Portal setting. I wondered why it wouldn't be available to the Site, so I copied it over to the skin folder. It showed up under the Site Skin's drop down, but I still can't get it to Preview without the resulting page still being Flex with the above URL. 

I'm supposed to go live this weekend, and can't solve another issue unless I get the default skin issue sorted out first. Any insight would be greatly appreciated.
