So I am cheating now? + Game crashing on Skirmish

[Infarlock]

Few days ago I installed a mod which gives more units to the game and played the singleplayer missions, I completely wiped the game and reinstalled it as I installed it before

Installed CNC and it updated to 0.28, I tried playing Skirmish to confirm that it works but I got "Yuri's revenge has encountered an error" Ok, so I had a nice game of multiplayer and just ended the day.

 

Few mins ago I installed the 0.29 update that was released today and now whenever I go to a lobby it tells this at the chat:

This message didn't appear for my yesterday and now people kick me from the lobbies, nevertheless I still cannot even play skirmish unless I manually open the .exe and play from there but the menu is slow af for some reason.

 

Would be glad to receive some help, especially with the Skirmish.

Alright so I just reinstalled the game again and it still gives me same messages, error at Skirmish and tells me that I've modded my files

 

Now it's 0.31 btw
