chips now need to be .PNG files
you need to edit
Code:
~/system/preferences/com.pokerstars.<your region identifier>.user.ini
and add the following line to the very top of the file.
Code:
[debug]
RunUpdateCheck=0
which tells the client not to update i.e. not to overwrite all the chips that you have just installed.
when you want to run updates, change the 0 to 1 and update the client.
