SQL 2005 Migration error

We're migrating our SQL 2005 box from an old Windows 2003 32-bit server to a new 2008 64-bit box and having a few issues.

We're trying to keep the server name the same (MANAPP03) but when we down the old box and bring the new one up to test, we're getting the following error in the reporting services:

Unable to initialise report server service after migration to new Windows server. Service starts but does not initialise.

I've attached a screenshot and below is the reporting services log - any help will be much appreciated as we're aiming to go live with the new box this weekend.
