Game crashes after buying mods in the store

[walkera16]

I downloaded FS2013 and a few mods for it but every time I open the game, go to the store and buy one of the mods my game crashes
iv eliminated all mods showing errors in the log.txt but it still keeps happening and when I try running the latest patch for FS2013 it says my game isn't installed I really want to be able to play

The first thing I would check is that the mods you have are for FS13 and not FS15.
Try taking all of your mods out (store them safely to put back later) run the game and see if it loads properly. If it does then one (or more) of your mods is likely to be the cause of your problems.
