My mojoportal is just started working yesterday, I am a new user. I downloaded "mojoportal-2-3-7-6-mssql-net40-deploymentfiles.zip" and installed it, everything is awesome. I would like to have a treview style browsing on the left side on the webpage, for that I read in the forum some other skins work that way (none of the existing ones though). 

I downloaded the extra skins file and saved them under "C:\inetpub\wwwroot\Data\Sites\1\skins\" path. I only have 1 website. My existing skins works fine but for some reason the new skins generate the error below. Does anybody know what that would be ?

Thank you
