Thank you for replying, sorry for double posting I won't do it again.
I see, so the patch 4.11m does not work with these mods. I had read the guides and they mentioned 4.101 and perhaps 4.101m (could have imagined that part) and since I couldn't find those patches easily in google search I thought 4.11m (apparently the most recent patch released this year) was the same as 4.101m.
You are right, backups are very important. I will retry with that patch and see how it goes.
Thank you again for your reply it was very helpful, I'm sorry if I seemed hurried.
