Hello so today I was working on my map and When I start up the mod the main menu has alien letters and when it loads in game its on a default ugx map and you cant move? Can someone please help me? as you can tell im new lol

Hey guys so yesterday I decided to script and make a map. Radiant was messed up and I decided to take off the UGX mod and just go regular. After that I found out how to fix Radiant with the textures ect but now when I start up the mod on the main menu there are like alien letters and when you go in game you cant move. Is that because theres no map yet? or what. Ive heard this problem before but I'm not sure what to do now  Thanks - Assassin
