Unable To Download Game On Steam

Steam will not download any game or update , for some reason however it will download the workshop files and updates
The downloads will be in que and steam will attempt to download them, but it won't do anything, it'll stay like this for a short amount of time (longest one was about a minute shortest was half a second) before giving up and moving onto the next one.
Things I've tried include:
Granting and denying access through firewall
Turning firewall off and on
Reseting files (steam/flushconfig)
renaming ClientRegestry.blob to ClientRegestryOld.blob
I do not want to remove steam and reinstall it.
Edit: it's not completely not doing it, it's doing it like 1 or 2MB at a time, explains why the workshop files worked.

Also, when I click play on the game to have it auto launch, it says it cannot download the game and in brakctes it says download corrupt. I have also set GTA V (one of the games not working) to a high priority. In addition to this, I can't boot up certain games which may have something to do with it.

I have an issue with the new bundle. I bought the above average, and I can't install any of them, nor can I download anything else or update anything. It just says 'An error ocurred while installing (game) (UNKNOWN ERROR)' Someone help please, this happens with everything in my library.

FIXED

Here are some steps to help troubleshoot your issue.

Download Game Onet

If you are running Steam on a PC:

Please exit Steam and go to the folder called C:Program FilesSteam (this is the default location for a Steam installation - if you set a different installation directory, you will need to browse to it).

Delete all of the files in this folder except:

The Steamapps folder and Steam.exe (this file is listed as an application and features the black and white Steam logo)

Restart your computer.

Then, launch Steam.exe from within the Steam installation folder, and not from a pre-existing shortcut.

With Steam running, re-test the original issue.

Note: This process will not affect your currently installed games.

If the issue persists, make sure your network is optimized for Steam.

If you are running Steam on a MAC:

Please exit Steam and go to the folder Users/[username]/Library/Application Support/Steam

Delete all of the files in this folder except for SteamApps.
