when i click play it says failed to start{missing executable}, i cannot contact steam nor ask on the forum, neither one takes my email address, why is this doing this.

Can you create a new forum account using your email?
You may have to have separate accounts for purchasing and for the forum.

I'm not the Steam expert, so someone else may have a better idea what's going on. I found this site using a search for
Steam "failed to start" "missing executable"
https://support.steampowered.com/kb_article.php?ref=8676-EFLX-7453

okay i will try both, i did neither worked on the forum. never mind i finally got it to work.
