I get the same error (Unable to initialize data dictionary) on a windows server 2003 32-bit installation with sql 2008 and slx 7.5.2 - but only on Web! The Lan client login works without a problem. I even changed the connection manager back to native 2005 and did a rebuild & deploy - but without success.
Kind Regards, Marco
