Supreme Commander is crashing on launch with an EXCEPTION_ACCESS_VIOLATION. It crashes with Setons maps but not for the 'Fields of Isis' map which suggests the problem might be related to water.

I think the problem started with a recent update to Supreme Commander. I re-installed Supreme Commander from a DVD and FAF from the web site but this has not helped.

The ' warning: GetResource: Invalid name "" ' messages in the log below might be significant. Please help.

Could you please indicate the current status of announcement 'Addressing Severe Connectivity Issues - What has happened!'

https://forum.faforever.com/topic/6182/addressing-severe-connectivity-issues-what-has-happened

When I play I still see far more disconnects than there used to be on FAF.

The disconnects usually involve two players disconnecting from each other while all other connections remain. The game stops and takes a few minutes to show who has disconnected from whom and then generally several more minutes trying to persuade one of them to exit so the game can continue.

Most games have at least one disconnect and it's common to have several disconnects in one game. Games are frequently won/lost due to disconnects as a player and all their buildings/units disappearing usually has a big effect.

I think the degraded game experience is making people leave FAF so they can play other more reliable games.

Looks like the underlying problem was caused by Norton Antivirus Data Protector.

I deleted the old 'C:\Program Files\Downlord's FAF Client' folder and down loaded the latest FAF client installer from https://www.faforever.com/

When I tried to run this I got a "Data Protector blocked a suspicious action by faf_windows-x64_2022_4_0(1).exe" message.

I managed to get Norton to exclude this process and then everything seemed to run okay.
