Thanks for the fast reply I did for the steam version what you said now i don't have any problems about the game

but I still can't add any mods on v0.30

The "Spaar's modloader" page is not working is it normal ?
I'm using the link in the "Precision building project 2" page under your NEW COMPUTER stuff
I tested other mods like your rocket thrusters but when I get back on the game it didn't change anything. I'm pretty sure to place the mods as writen and the good version of the mod (I'm always taking the latest or the only one of the page) but it just won't work.
I've already used your mods months ago (before the 2nd island) and I had less problems
