That's really odd. Are you from a country that uses commas instead of periods to separate whole numbers and decimals? Like one dollar ninety-nine would be written as 1,99 for you? There is a known issue in the older versions of the game where this particular culture difference caused issues with mods that is fixed in a new version coming out later. If not, then the only thing I could ask for at this point would be a video of the whole install process to confirm there is no mistakes. Otherwise you may have a unique issue that is caused by some other regional difference in PCs.
Okay, that's good actually, it's something you might be able to fix on your own if you want to play mods before the next update comes out. Try going to the files for ARK, and open the Class.txt file. Scroll to the bottom part where you see Attack and Skills, and the NormalCol, SpecialCol, and BellyCol sections. For Attacks and Skill, make sure they are separated by commas. For NormalCol, SpecialCol, and BellyCol there should be periods. You do this quickly by using the replace tool that comes with the standard Notepad program on Windows. Tell it to replace all , with . and then just go back to the Attack and Skills section and put the commas back in. It might not work since it has been a bit since I have messed with this issue, but it is worth trying.
