In demo game, I always change my club account to 2 billion pounds and 1 billion for transfer
Just to test with many option when you buy player: outside EU, first option.....

-------------------------------------
If you just want to change money of club, and you don't know about artmoney. ok follow this:
1. open your game in FM
2. open your club financial tab
3. Remember the money which you want to change
4. Alt+tab or windowed button to jump to desktop
5. Open Artmoney
6. Change to FM in select process
7. click search and type number in step 3
8. After it's done, alt+tab to the game and do something to chang that number in step 3 (eg: buy player or wait few day ....)
9. Switch to artmoney, and click filter then type new number
10.It will show few number now. If it happen, continue do from step 8 again, (not start new one, just continue do from step 8 again)
But mostly, it will show only result, click red arrow button, then click on that number in right window, and change to the number you want (that will be new money of club)
----------------------------------------
Note: sometimes, after step 7, it shows few result, you can click to green arrow button, and change those number
eg:
value 1 change to 1m
value 2 change to 2m
value 3 change to 3m
.....
when you switch to the game check your money, it's 2m now, so the right address is value 2, you can delete value 1 and 3
-----------------------------
if you have searched 1 right value, you want to search number of money of something another in game, when you search some results will shown, then check address with few beginning charater same as the address you have
eg:
you have value with adress 0fb833d6 is right in game then you search if adress have something like that 0fb8..... so maybe it's the value you want to find .
