HELP! RA2 online cncnet lags out after 5 seconds after MCV deploy

[Wills]

Please help me CNC net community.  I have been playing RA2 YR for years now on cnc net. Few months back one evening the game suddenly lagsout just after all players load in ~4-5 seconds after deploying MCV and building power plant. The game was working fine all evening before. But ever since, despite installing each recent patches and updates this happens ever tiem (whether i am host or joining player). Has anyone seen this and have any ideas how to fix?

 

I have tried - disabling firewall and antivirus, run admin, changing compatibility mode, and am reluctant to uninstall I did it back when my PC was win 7 (now Win 10) following a YouTube instruction and am not confident I will get game working again (I can still play skirmish currently against AI).

 

Many thanks!
