Loads of errors?

[leer 1]

Having several issues-

Firstly, as soon as I start the game up a pop-up box comes up and says 'profile not found .prof' or something like that.

Then when I'm on the main screen it says 'no entry, 'bin/config/rschint/background.type'

Then it says 'bin/config/cfgvehicles/land_shed_m01.camouflage'

Then finally when I click join it says 'You are unable to play/edit this mission, it is dependant on downloadable content that has been deleted.cacharacters_pmc

Help please!? Took forever to download, so I REALLY don't want to download it all again - I just tried installing this http://dayzmod.com/forum/index.php?/topic/48329-hotfix-build-1724-rolling-update/ and I think I did it wrong, extracted it and overwrite some files? :/

New, so any help is VERY wanted! :)
