Hi Graham,

I know I should have elaborated more but I was very short on time at 
that moment. It was a missing dependency.

It was nss and I was pulling away nss dll files to see just what was 
needed and what wasn't. Interesting was that the error was different for 
most but that error came up for some. The other was

[Fri Mar 30 18:12:05.018600 2012] [session_crypto:error] [pid 3404:tid 
700] (OS 126)The specified module could not be found.  : AH01845: The 
specified module could not be found.

This does give better info
[Sat Mar 31 10:15:59.017600 2012] [session_crypto:error] [pid 4932:tid 
700] (100005)Error string not specified yet: AH01845: The crypto library 
'nss' could not be loaded: (null) (Error during 'nss' initialisation)

Maybe however, "Error string not specified by the driver yet" or 
something to that effect? It cannot be incorrectly read as "we're not 
sure what to say here yet," as I embarrassingly did.

Regards,
Gregg

seems to be bogus, this won't help with the message, but will in theory give a hint to the
