Hello,
what is the language of your pokerstars ' software and your pokerstars ' handhistory ?

You need to choose english if you want it s work all the time.
By the way, i found something wrong with pokerstars ' software in Italian, it will be ok on the next update.

okay! Problem solved before reading the answer
I just had to set the language of the whole lobby ps in English!
I downloaded the 30 day trial Holdem Manager to understand the problem, but it's all right now. On March 19, I do the update for one year Xeester!
P.S: if you really should ask for advice I am for my eyes!
The skin of Xeester program is too dark for my eyes that the view is blurred after a couple of hours and there is no clear skin to choose from. Council for my eyes
