I found the problem and solution ! I'll try to explain it as clear as I can with my poor english. I saw other people had this problem and I bet for the same reason.
I opened my usb again and looked at the fast shower mod and I found 2 files instead of 1. First one had ._ symbols in front, another didn't, the rest was identical. So I transferred only 1 file without ._ symbols and it worked !!!
Then I went to the cc file and saw the same thing. Each cc peace I have was duplicated. First column had all cc files with ._ in front of each file, second column had no ._ symbols. I chose second column, placed it in game AND IT WORKED !
I would post pictures if I would know how to make screenshots on pc but don't know how to do that yet.
