Did you get anywhere with this?

>>>I have a back created on SQL 2008, and I'm trying to restore it on another machine also running 2008.
>>>
>>>I'm getting:
>>>
>>>

>>>System.Data.SqlClient.SqlError: The database was backed up on a server running version 10.50.1617. That version is 
>>>incompatible with this server, which is running version 10.00.2573. Either restore the database on a server that 
>>>supports the backup, or use a backup that is compatible with this server. (Microsoft.SqlServer.Smo)
>>>

>>>
>>>I was able to restore it to another PC running 2008 R2, but not this one. Is there any way to restore this DB on this PC?
>>
>>The version the backup is from is SQL2008 R2. The server you tried to restore to is NOT R2. They do not play nice in backup/restore.
>>
>>Either upgrade the 2008 server to R2 or copy the database from the server you did restore the backup to.

>1) Is there an 'upgrade' or are we talking a full install?
>2) Will I still be able to access all the other DB's currently in 2008?
