MODS Doesn't work for me

My problem is that I have been trying to join a server that requires a mod to let me join. The server is addressed at and the mod in question is Conan Sexiles. Now my problem is that I can’t get the mod button on the main menu page to work. So, I can’t enable the mod. Even though I subscribed to it. Every time I press the MOD button on the main menu page, the page freezes and I need to press the Control, Alt, Delete buttons to get out of the game. Is this a common page.
