Problems when moving to a different server

[steveo]

We tried to move our Ablecommerce site (version 7.07) to a different server yesterday. Bothe servers are running at the same host with the same environments. We are using the same domain name. After we switched the dns we go the following message:

The AbleCommerce license is registered for c:\hostingspaces\dvgrr\store.dvgrr.net\wwwroot\,
but your application is installed at c:\hostingspaces\qns2012\store.dvgrr.net\wwwroot\.
Please update your license file or move the installation.
To learn more about license keys and how to update, click here: AbleCommerce License Help (new window)
To update your key now, click here: Update Key

OK so I log into my Ablecommerce account and request a new license key. When I click on the link to update the license I get this error...

Server Error in '/' Application.
Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same. If the server is on a remote machine, please ensure that it accepts remote requests by checking the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aspnet_state\Parameters\AllowRemoteConnection. If the server is on the local machine, and if the before mentioned registry value does not exist or is set to 0, then the state server connection string must use either 'localhost' or '127.0.0.1' as the server name.

Any ideas what to do now? I did try restarting the app pool but that did not help at all.

I restarted the session state server and was able to update the key. However now I am getting this error... HELP!!!!!!!!!!!!!!!

Have you made changes in your web.config regarding what is used for session state? Here is Able default:
<sessionState mode="InProc" timeout="30" cookieName="AC7.SESSIONID" />

Just edit the /App_Data/Encryption.config file with Notepad. Remove everything between the <encryption></encryption> tags. Save it. That will get you past this error.

Encryption keys are machine-specific. When you move the site, you must make sure you've backed up your encryption keys prior to shutting down the old site. Then restore those same keys to the new site once you have it lit up.
