Repost: Help with .Net and Informix (marked as question)   

I am trying to connect to an Informix server in visual studio. I have installed the IBM Database Add-ins 9.5.1.39 (v9.5fp1_nt32_vsai.exe) and the 290MB Client.zip
However when I try and connect to the Informix server in VS.Net's Data Connection, I get an error.
Here is what I put into the wizard:
1) Choose the Data sourceas "IBM D2, IDS and U2 Servers"
2) I enter server name, e.g. servername:port
3) I enter the UserId and password
4) I manually type in the db name as the drop down is blank?
5) click advanced and put Server Type as "Informix"

When I click OK I get the error in the attached file.

Please could someone please tell me what I'm doing wrong? Our Informix server is IBM Informix Dynamic Server Version 11.10.FC2
