Inbound email setting problem - Gmail account - 7.8.3 Version, windows 8

Hello everybody.
I’m facing a problem in setting my gmail account with Suite for inbox folder. Even If I fill all the datas necessary for the setting, when I have to choose the folder the systems locks up and shows a progress bar that never disappear (as you can see in the attached screenshot). This thin happens only with gmail account, since I tried to configure other not-gmail e-mail addresses and everything works.
Could you please help me solving the problem?
Thank you,
