McDingleBottom The problem doesn't seem to be about installing. File corruption happens either 1. during transfer through the internet or 2. when saving on your HDD.
1. You have no choice but to try to download again. Since I'm working on an updated version just wait for me to be done.
2. Your HDD might be damaged. It's unlikely a virus corrupts the file but not impossible. In this case you will have to run a scan of your hard drive: https://www.lifewire.com/how-to-scan-a-hard-drive-using-error-checking-2624497
Blstel , 650132 Post your problems and findings in https://forum.cosmoteer.net/d/4923-game-crashing-on-0-13-6-mod-version-5-0-0 I'll see about it after I've made the mod compatible with 0.14.0 which I project won't be happening for at least a month.
@IVIemories Kudos for you! Thank you for covering for me. You can rest now my friend.
