OP, I know that waiting can be kinda stressful, but it's just two days since I reached their rep with PM and they haven't been online from the day before I sent my PM, so there is a very big likelyhood that they are yet to notice my PM. If you don't mind to wait for a couple more of days, see if they returned to the forum around that time, it'll be very much appreciated.

I think I have their rep's personal contact, though I have yet to ever reach them there, so rest assured that if by [let's set a deadline here] Thursday they are still not yet online and address your matter, I'll try to find a way to gain their attention and bring them here to address it. Does that sound good?
