Hey, just now seeing this ramble I’ve had this problem before it’s actually something that I discovered from another friend of mine as a workaround, but it does fix the problem. Basically what you have to do is go to your registry and I believe it’s called local H machine and down arrow to the steam directory inside of their remove that directory uninstall steam and reinstall it and that will put the steam client in English then you will be able to login with your account. Hope this helps if you have any issues please feel free to reach out.

I hope you can figure it out. It is really annoying that it does that.

Thanks guys. I've tried to reinstall it in the past and it hasn't worked but I'll give it a go.

I had this problem as well. I reinstalled it, but it didn't fix it. One day I loged on and it was in english. So I guess it fixed it self or it finally noticed that I had english as my language.
