You read the 1st 3 words and thought "Oh no not again" lol :P But this time how do I use my maps I made in TGE demo in TT , I copyed all the.mis and.ter and other files in to the tt missions and rename one of the TT_1.mis with my.mis file and all I get is invalde packet error, so plz :[

You have to edit the terrain block in the.mis. Change what needs to be edited (ex: game/data/missions)

You cant start with a TT original map
It will give you errrors
Start with a dash or a napalm or a rooster
Anything but an original
Then provided you placed all your shapes and skins in exactly the same
file structure in TGE as in TT you should be good to go
Everything must match - it cant load what it cant find

I'll try that

I didn't see anyhting mentioned about duplicating the demo folder and renaming it game.

Are you still working from within the demo folder in TGE? If so, it wont work, The paths to the elements will be wrong.

Oh okay I try that now :) , but should I paste it in the tt folder or what

No you should follow the instructions for TGE which state
"copy and paste the demo folder and rename it to game"
"then add all TT elements to TGE game folder so they are mirrored exactly"
"then start with a 3rd party map......"
