I've reviewed you're reported error and a few things jump out at me as basic questions to ask in order to see if this issue can be broken down further.

 1. Are you able to even launch in the install wizard page?

2. Assuming #1=Y, Did you choose the 'Auto' Installation on the Install wizard?

3.  This error mentions 'AutoGenerate cannot be used in a cluster.'  Do you know if your host is using a cluster?  What is their cluster configuration.  It appears that when the viewstate is reloading on the page it is finding that the MAC is different for the system you are on.  Is it possible your ISP has their configuration as RR so that each request may jump from one box to another?  If so, they may need to check their Cluster setup to ensure that all of the servers share the appropriate Security keys to allow proper maintaining of statedata integrity across page loads. 

4. What kind of access do you have to these servers?  Full-unrestricted; simple hosted with shared hosting and no direct access?  This answer may help to prove out also if there are other permissions issues.  Does razorhost offer a pre-packaged DNN Instalaltion?  

 I know I've probably asked a lot, but those are just a few things that jump out at me from this error that you may need to look into. 

Recommendations:

1.  If you did use auto-install try using 'Typical' and see if that makes a difference.

2.  If you are using a cluster environment, ensure that when you enter a servername say for SQL you are using the clustername, and not an individual server name in the cluster.

3.  Post back with any of the information you have, and with more information perhaps a more definite cause can be determined.

Hope this Helps!
