Hi
I'm hoping one of the experts out there will point me in what is probably a very obvious direction.
I have had an installation of DNN installed on a server that I don't have direct access to, but I do have Admin rights. I keep getting a Page Load Exception, which is causing a Critical Error: Failed to load viewstate error. It doesn't get triggered by the same thing and has happened when clicking on the Login link, while trying to login, when trying to delete a module, while trying to apply skins to portal or admin areas.
Here is the error from the Event Viewer:

I am hoping it's simply a server setup problem and I can direct the server tech people to fix it, but maybe it something else that I'm not clued onto. Would upgrading to DNN 4.8 help? Should it be an upgrade or a clean installation?
If someone could help that would be great. Cheers, K
