Upgrade SQL Server Beta 2 to Release

Hello,

I try to export a database from one sql server (beta 2) to another (release).

Both server can see each other, but I cannot create a connection.

From release I get the error message:

TITLE: Connect to Server
-----------------------------
Cannot connect to COCHRANE.
------------------------------
ADDITIONAL INFORMATION:

Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding. (Microsoft SQL Server, Error: -2)

For help, click: http://go.microsoft.com/fwlink ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=-2&LinkId=20476

------------------------------
BUTTONS:

OK
------------------------------

And if I try the same from beta 2:

TITLE: Connect to Server
----------------------------------------
Cannot connect to mul044\sqldev.
----------------------------------------
ADDITIONAL INFORMATION:

Failed to retrieve data for this request. (Microsoft.SqlServer.SmoEnum)

----------------------------------------
Failed to connect to server mul044\sqldev. (Microsoft.SqlServer.ConnectionInfo)
----------------------------------------

Unknown ProviderServer doesn't support requested protocol  (Microsoft SQL Server, Error: -1)

For help, click: http://go.microsoft.com/fwlink ProdName=Microsoft%20SQL%20Server&EvtSrc=MSSQLServer&EvtID=-1&LinkId=20476

----------------------------------------
BUTTONS:

----------------------------------------

What can I do to export my database from beta 2 to release
What is the best way

Thanks a lot.
