So there is a simconnect.dll in the fsx main folder and its version 62607. In the WinSXS folder there are 4 versions of the simconnect.dll, versions 60905, 61355, 61637 and 62607.
When i reinstalled FSX-SE it was not from steam, its version 10.0.62607.0.
The attachments are what the event viewer logged about the crash
About the .ini file, going through the user manual on the day of this first happening I deleted the contents of the modules folder all at once to reinstall FSUIPC. Later going through the forums I thought these would be necessary, so I retrieved them from my recycle bin and put them in a folder on my desktop. I do not know why there is no INI file from any use over those 3 months. I have since deleted them all and started it again to no avail.
