Hi!

I am trying to decrypt a text, but I cannot find the right way to do so.

After trying several combinations, I dont know what I should try next.
What I ve done is to find out the letter frequency.
d : 20
y : 15
q : 13
r : 13
a : 12
n : 10
h : 9
t : 7
m : 7
c : 7
v : 6
u : 5
f : 4
i : 4
p : 4
s : 3
x : 3
l : 2
j : 2
e : 1

I am a beginner, please, dont be hasty...

I am still without result ...
is there a trick, how I get to the  result.

I try it more or less like bruteforcing....
