There's no useful information for me there I'm afraid. Did FSUIPC4 even load? If it did start there will be a log file -- FSUIPC4.LOG in the Modules folder. If it didn't then the problem is either elsewhere, or it is still the SimConnect bug as described and discussed in that FAQ thread I pointed you to.
All using the Loader is doing is delaying the crash a little. However, if all you did was "put the FSUIPC Loader into my modules folder" then it isn't being used in any case. You would have to re-run the FSUIPC4 installer after doing so to make any difference. Really you do not want to be using the Loader.if possible in any case.
In all previous cases, persistance has paid. Once SimConnect has accepted the DLL it is okay thereafter.
I'm afraid I've no cure for this problem, which afflicts only a small number of installations. I've got three separate installations and have tried everything to get it to do the same here, all to no avail.
