UIG has released 4 versions of ag sim and Every one has had exactly the same bugs on release
,2013 has had 8 months to get fixed and it's still crap - i'd promised myself i wouldn't buy another version but is decided to grab it a couple of weeks ago when the gold version was on sale at gamersgate ,anyway i knew there was going to be problems when i installed it and it crashed when i went to make an account,(yes online drm which means you can't play it offline when uig's servers go boom!).
After that fun i tried to update it download patch ,install then crash - rinse and repeat till it's up to date
Get the thing running then the fun really started ,between crashing every 15-20 minutes I had issues with implements sliding under the tractor so not being able to hook them up in the tutorials ,or restart after a crash and the implements floating in mid air and separated into it's component parts
The recommender system requirements are an out and out lie ,I've got a system that smokes the recommended but to only way to get acceptable frame rates is to turn all the graphics options to low - when it was released on steam ,one of the devs admitted that to get the kind of images in the screenshots you needed an Nvidia Titan card....
Get Farming Simulator 2013 instead ,not as many options but it works and there's a ton of mods and maps for it if you want to change the default gear.
