Required permissions cannot be acquired

I just downloaded my Mojo web site and database from Seekdotnet and attempted to set it up on a virtual server.
The server is Win 2008 Std. NOT joined to a domain. SQL Express 2008 R2. I've given read access to Local Service, Network Service and IIS_IUSRS to the whole site and read/write access to the data folder.

My web.config file can be found here http://dl.dropbox.com/u/15481718/web.config

Any pointers would be appreciate. The error message is as follows.....

Server Error in '/' Application. --------------------------------------------------------------------------------

Re: Required permissions cannot be acquired

Hi,

It sounds like a Medium Trust problem. Deleting the DotNetOpenAuth.dll from the bin folder should solve that specific error, it doesn't work in medium trust and is not needed unless you sare using OpenID authentication.

Hope that helps,

Joe
