My DLL's are (in the correct order):
I made a quick check on these and, according to their manifest file, they requires the following Simconnect versions:
LHBP_objectPlacer.dll (LHSimulations Budapest) - 10.0.61242 - FSX SP1
AFXModuleFSX.dll (Airport Facilitator X) - 10.0.60905 - FSX RTM
ViMaCoreX.dll (Vistamare) - Doesn't have a manifest, it probably loads Simconnect dynamically.
AS-FlightRecorder.dll (Aerosoft Flight Recorder (Airbus series)) - This one includes ALL different Simconnect versions in its manifest file. This doesn't seem to be a good idea, according to this post on a MSDN blog:

FSUIPC4.dll (FSUIPC 4.944) - Doesn't have a manifest, so it loads Simconnect dynamically.
I don't have the as_btstrp.dll, but I tested other modules too:
PMDG_HUD_interface.dll and PMDG_Interface.dll - 10.0.61259 - FSX SP2
ObjectFlow.dll from OrbX FTX - Doesn't have Simconnect referenced in the manifest, but the are references in the code to the 10.0.61259 ( FSX SP2 ) version, which seems to be loaded explicitly.
LeonardoSH.dll (from the Maddog) - 10.0.60905 - FSX RTM
LVLD.DLL - 10.0.61259 - FSX SP2
SimObjectAnimationModule.DLL ( SODE ) - 10.0.61259 - FSX SP2
To sum up:
1) PMDG, Level-D, SODE, ViMaCoreX, FSUIPC4 and ObjectFlow.dll all require the latest Simconnect version, the one released with FSX SP2, either from their manifest, or by loading it dynamically, so they cannot have been the cause of the problem.
2) LHBP_objectPlacer.dll requires the FSX SP1 version, which DOES have the Simconnect_text() function call, so this wouldn't be a problem either.
3) AFXModuleFSX.dll, RAASPRO.dll, and LeonardoSH.dll require the FSX RTM Simconnect, so any of them might have caused this. However, I use AFX myself, and never had a problem with it, regardless of the loading order.
4) AS-FlightRecorder.dll - This one look odd, so I'll try to test it more now...
