I deleted my CFG and when the new one built it ask me for permission to install FSDT and I denied and FSX started okay.
I went back and repeated the excercise and accepted permissions and this caused a crash again.
If you do this, you are causing the crash. Each bglmanx.dll file should be used with its accompanying set of bglmanx*.dat files, and both are updated when there's a major update. If you don't allow to the the new bglmanx.DLL, the old one will be forced to work with the new bglmanx*.DAT files, and this WILL cause a QUIT (not a crash) on start.
For the same reason, it's possible your antivirus, or other similar security related product, has caused the problem that lead to try this in the first place: if that program blocked the .dll from download but accepted the .dat files (antivirus blocks executables only), you end up in the same mismatched situation as above.
Be sure you turn off every program that might block the executable and/or the download, like an antivirus, anti-spyware, firewall, or similar, and reinstall using the most current version of the Stand-Alone Addon Manager.
