Cannot connect to GMail,Hotmail & Qatar mail since upgrading

I have recently upgraded to the latest version of Thunderbird Portable and since then I cannot connect to my GMail or Hotmail or Qatarmail to pull my mail down into Thunderbird when connected directly to the internet via DSL in my house with my desktop pc or my laptop pc but in any internet coffee & dailup connection i have no problem.

Has anyone had this issue or is experiencing this issue.
