If you're logged in and you get an error about requiring registration just log back out and then log back in. This should solve the problem. There is also the possibilty that some MT3.x cookies may be persisting. These are not compatible with MT4. Might be an idea to check what cookies you have referencing bowch.co.uk and deleting them.
