Game isn't starting

[CheshireNut]

  I tried to get rid of the version.txt but everytime I open LM up, the version.txt pops back up in the folder! I have a Windows 8.1 Laptop. Help please!
 My friend wants me to play with her and a friend but I cant cus of it.

It's supposed to do that, when you start up LM what is it doing? Does it just close, is there a black screen? We need a little more information.

[CheshireNut]

It opens up then updates then just closes and nothing pops up.
It may be security tho.

Try to run it as an administrator? Sorry if that doesn't work.

[Myz]

then you have a firewall blocking it

[CheshireNut]

Figures.

[Myz]

just disable it or add an exception

What Anti-virus program do you have?
Because Norton and I think Mcafee or something like that, are notorious for stating that LM is a virus, which it is truly not. So if you have one of those programs, I suggest you do as Myz stated above.
Personally, I recommend Microsoft Security Essentials I've had it for a few year now, and it's done a mostly very good of a job, except for like, three exceptions so far
Hope I helped!
