Pc Fc 26 not launching after a week (3rd repost)

I have played the game for a week then suddenly the game stopped for last saturday and havent played since. Been trying for so long to fix the problem with endless searching. I haver done evrything form updating and instaling and clean instaling windows.

The prob is that i load the green fc 26 and then a blakc screen comes and then its says "failed to launch and its on ur end". I can play evyer game i have on my pc and even fc 25 and i have a high end computer with evrything updated. 

I found the problem myself by getting my friend to log on to my acc and try lauch the game and he himself couldent get in on the game. He can play on his main acc but cant play on my acc jsut like me. THere is soemthign conncetion issues with only my acc to the server and not corrupts files etc. I can acces my webb app fine. My acc is litterly bugged.

I played rivals totaly fine that day, then the game suddenly stopped working and then i ended up never getting in to the game again. I have played multiaple games that day and i had my suspicions that the guy was a ddoser cause they game ping said i had 16 ping but felt like 200-300 ping hole match. Game ended 5-5 and after the game i couldent get in to the game since.

I have been struggling for a week trying to get it to work since ive have spendt some money and invested alot of time. I would really like this to get solved since it cant be on my end of the problem since me and my friend cant lauch the game on the acc
