hi my ets 2 and promods are all up to date and loaded in the mods folder and correct order for ets2 but when loading into game after sorting the mods i get black screen then kicks me bk to steam. im still using the promods trailer and company from the previous update. any help will be great

I know that ive done that but dose it stay on your account so it can be downloaded again or is it just a redownload

ive bought promods on my old pc and now sold it. I forgot to put files on to usb. will I need to buy them all again.
