Not a bump, it was a video in positive response to the map post, it was very on topic and also shows that it works great in the current version of BeamNG.Drive.
1st of all, great bump. 2nd, why are you using such an old version of the game? Are you a pirate or something?
There is no official way to downgrade your copy of BeamNG to a pre-0.3.8.x version. Unless you're either a pirate or have backups from about a year ago.
Interesting how you have access to those versions when you joined Friday. Maybe show us proof you have the latest version?
He is speaking of you posting on an older thread. I can't download this map right now but I'm going to guess if you open the zip you find the maps name as with most older mods. Just make some new folders in your mods folder. example [Documents\BeamNG.drive\mods\unpacked\(name of folder in zip.zip\levels\(folder in zip)] That should make it show/load ingame. If it does not msg me and I'll help you out.
