Skyrim stopped working help please

[76561198081883450]

I have been happily playing skyrim for a while now, but up until a few days ago when i tried to open it up a message popped up saying that there where some data missing or something like that the message displayed a link bringing me to some info on the problem; it told me to exit steam then look through my steam folder, delete the appcache file, restart my computer then reopen skyrim on steam, so i did everything it said up untill the point when i clicked "play" all of a sudden anouther message pops up saying:

"failed to initialize renderer. Your display doesn't support the selected resolution. Please set a different resolution in Skyrim's launcher under 'Display Settings'."

What to do from there? I have no idea how to do any of that.
Any help would be great
thanks

Yeah, set the resolution there to whatever resolution is "native" to your monitor.
