[Good-names93]

hi guys can someone help me please?.. im trying to install a mod track from mxbikes shop but when i put the pkz file into the motocross track folder it doesnt show on the track selection in game... but if i put the server version it appear but there is no track data when i start playng. how can i fix?
ps.it s not my first mod installation , the mod is compatible with  beta 18 so i cant figure it out what it s wrong... i also stopped the sync from one drive but nothing.

I don't think the server files are locked so it might an issue with your MXB GUID on the shop. Check your GUID is correct on the site and maybe ask for support on the MXB shop site, there's a discord link there.
