Typically IF there is a captcha, a popup should appear, and it should say solving catpcha at the bottom of the main PF window. However I haven't done manual solving because I have been lucky with 2captcha not failing me at this time. Let's get you to turn off all firewalls, all antivirus programs and do a nice fresh install into a new folder (from there import your Logic Settings and redo your main settings) and test it out. I know you have tried already and set exceptions, but I just wanna make sure there is absolutely no funny business going on.
