popup won't fully open

just saw your post today. i have a 2008 850sc bought uesd Last saturday we left a camp ground and drove 150 miles to another. went to raise the top and the passenger side did not go up.Thought I had forgot to open the hasps or lock downs on that side checked and they were unlatched After about 20 minutes of messing around trying to figure out what was wrong, noticed the pin in the passenger side"lift gear" was missing. did find it laying below the crank area. put it back in and is now working ok. Did you find any reason why yours is not operating? You might call the northstar folks. I ask them a question on putting in a a/c as to where to cut the top. They responded within a couple of days. would like to follow this post. Don't find much info on the northstars, maybe that is a good thing.
