bf 5 does not start

hi all,

at certain point (probably related to ea app auto integration) my bf 5 stopped starting at all, despite hundreds of hours played in the very same PC set up.

i purchased it at steam, and it alwayes worked. but now it just doesnt.

cache clean, reinstall, all that - not helping... 

this irritates me a lot , and total lack of support - irritates even more..

is there a solution?
