Anti-Virus can interfere with the launcher's work. At least after the update, I ran into this and added the file I need in the exceptions. After that, the game earned.

Anyhow in the past few days there has been an release of an new patch. My bet is that you are running on the old files from before this patch due to youre system restore.
Try to reinstal disco, download the latest version and you should be good to go.
The game loads to the point that I can see the server list (which only shows RP 27/7), but the version (89.2) shows up in red and won't allow me to select it.
Although I don'w want to, I can feel a reinstall marching with inexorable inevitability in my direction
That is why you need to redownload... Version 89.2 isnt the current version. Due to the system restore you had to do the new version is no longer pressent. You can try to do an manual patch but im not shure where that link is. But if that fails i recomend an reinstal
