having diffiiculty joining LMS co-op

[Faceball 2000]

I've played Doom 3 in multiplayer, but it's been a while and I've upgraded my laptop to a Windows 10 64 bit - I don't know if that's the problem, but anyway, even after installing the last man standing co-op mod, after running it, the screen tells me I "don't have files required to join server" - why?

If that's EWZ LMS Clan server then you have to rename lms4 folder to simply lms and rejoin, If that doesn't work try with Multiplatform version of LMS (assuming you're using Normal Installer), After renaming the folder of course.

Thanks, one thing though - after renaming it's asking me to merge, so I merge the folders with the .cfg and .dll files?

Yea, merge and see if it works.
