Problem moving database to a new server

I have been having problems with my current MSSQL2005 server, so I've decided to move my PC database to a new server. The site files will not be moved, only the database.

I have had server technicians copy the database to the new server so that I can test everything before I make the switch. To test, I have edited the storeconstants.asp file to the reflect the new server connection. I can see that the store is in fact connecting to the new SQL server (I made a simple edit to a product and can see it reflected in the store). I can also navigate the store, add products to the cart, etc. without problems.

But when I try to log into an existing account, either to place an order or view account details, I receive the following error: "An error has occured in this store. We apologize for the inconvenience... The error has been logged in the store database. The reference ID for this error is: . Write it down..." As you can see there is no reference ID, so I cannot look into the specifics of the error.

Is there something else I need to do besides change the connection details in storeconstants.asp? I can see the account in both databases, so I assume that the database has been copied properly. The error also occurs if I try to setup a new account during checkout.

That is your license key.  If changed, encrypted information in your store will become unreadable. 

I suggest that you file support ticket with EI.  Something is causing dberror.asp to be displayed.  What that might be cannot be determined without FTP access and physically examining thing.
