Linked server to firebird

[deepsheep]

I'm trying to integrate some data into a new system. The existing system is a Firebird database and I can't move away from it.

So, I'm trying to create a linked server to this Firebird database. I created one on my local machine (XP pro, mssql 2008 express) and it works great! Moved to my server (2008 r2 server, mssql 2008 r2, 64 bit) and I can connect, but I get the following error when I try to query:
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "firebird" reported an error. The provider reported an unexpected catastrophic failure.
Msg 7311, Level 16, State 2, Line 1
Cannot obtain the schema rowset "DBSCHEMA_TABLES" for OLE DB provider "MSDASQL" for linked server "firebird". The provider supports the interface, but returns a failure code when it is used.

I had to use the SQLOLEDB driver to connect to the firebird driver available here:

I used this procedure :

I made sure to grab the 64 bit drivers.

I have tried the "Allow Inprocess" check box with no love...

Any ideas? Why it works on one computer and not the other? How to get rid of the error?
Thanks!
