can you please check you're running under .net 4.0 as older versions of .net did not support lambdas (you can log in and see this under host->host settings)

very odd - I've seen similar issues in .net 3.5 when it was running medium trust, as MEF (the failing exception) needs full trust in that version - however MEF doesn't care about trust in .net 4.0. One other suggestion I found was to set the "load user profile" to true in your application pool (note: that doesn't make sense to me as there are thousands of dnn 7.x sites not using that setup - but perhaps there is some oddity of a shared hosting IIS setup that causes it so it's probably worth your time to see if you can make the change)
