Hi!
First of all, I'm so sorry about my English and my grammar. I may have found a fix for the ones who have problems with the counter - counter stays on 0 -.
I tryed many times to install this counter, but it never work out for me. The black screen - A.K.A GilanGDXFonter - never showed up to me.
I unistalled PokeMMO, made a fresh install and installed the counter again and.. it worked! A few moments after, I've installed some mods - the same one that I had before the unistall process - and I've found out that there is one single mod that conflicts with the counter. The mod is: Generation 8 Style Icon.
Whenever I put this mod on, the counter stops working.
I don't know if this can help some of the users that had this problem, but I hope that it can helps.
