I am glad I found this thread!
I have AIS 5.0.594 and I also use Nokia Ovi Suite 2.2.0.245.
Via ovi suite I have been able to log into my nokia ovi account. After I installed AIS it is not possible. I get a error message from ovi suite that there is something wrong with my network settings. I have, in the FW section of AIS, set nokia OVI suite to full access and ask. That dint help.
I tried to disable the FW in AIS and then I was able to log into my nokia account. If I uninstall AIS I can log into my nokia account as well. Any ideas how to fix this so I can use my ovi suite without having to turn my security down everytime I am connecting my phone to my computer??
This is a AIS problem, not a nokia problem!
