[mapguide-users] MG2.4 Feature Source FDO Error 559 - Connect Failed

I am currently running MG Version 2.4 x64 on IIS running PHP, which I have
just upgraded to from MG 2.2. My problem is due to a number of data
connections which were previously working properly, but now appear to be
broken or improperly linked.

Below is the error message given by the log files when I tried to "Test
Connection" for an SDF Feature Source in Maestro (I recieve similar messages
when trying all other data connection types too):

<2012-07-23T09:26:55> 	2016	MapGuide Maestro v4.0.1.6639
 Error: An exception occurred in FDO component.
        Error occurred in Feature Source
An exception occurred in FDO component.
        SDF connect failed. File does not exist or cannot be opened in

>From what I understand, my main issue is that the files mentioned in the
error message actually do not exist on my computer, as I have been unable to
locate them. I have also checked the FDO directory in the MapGuide
installation, and all of the correct DLLs appear to be there, as well as the
providers.xml document which looks correct. I am presuming either an error
on my part when installing MG2.4, or an error with the 2.4 installer on my
machine is to blame; although I believe the former to be more possible since
I am still new to MGOS. On that note, my apologies if this is a trivial

Can anybody please advise me about what the next best steps to take would
