GSX crashed after I release parking brakes

[DJSJH]

I have problems while using GSX while at any THIRD PARTY sceneries.
I got no soundpack while pushing back. Couatl Engine crashed after release parking brakes during pushback for the reason "unknown". This happened after I updated my GSX few days ago. The version of GSX is the newest, and re-install or Live Update did not help. I don't know what to do next.

Your executable is dramatically outdated, like year's old:

couatl v4.8 (build 5237)

Current version we have online, which you will get when performing an update, is build 5459, so you are hundreds of builds behind. As usual, be sure the antivirus is not blocking the update, by adding the whole Addon Manager folder to the antivirus EXCLUSIONS, then run another update.

Okay, but could you please tell me which updater should I use? I tried both "FSDT Live Update" and "FSDT Installer" many times before. All the antivirus are disabled.
