Byte Array objects cannot be converted to strings Error-- SQLExpress DB

[floppo]

Hi I recently upgraded one server to be using SQL Express 2005
Now when I try to output the value of a ROWGUID its giving me this
Error Occurred While Processing Request
ByteArray objects cannot be converted to strings.

This was working with SQL Enterprise
<cfquery name="GetUser" >
select * from NewsFeedUsers where Email = '#Trim(Email)#'
</cfquery>
<cfoutput>#GetUser.Cookie# </cfoutput>
In the databse cookie = something like {6B02F6E3-33AE-47D5-9778-4C1968C68EFC}

How do I work around this? its killing me
Thanks
Paul
