I can't log in either, and you are the first person to report the same problem
I have not been able to log in for almost 2 weeks, only every so often I manage to log in, it gets stuck on the blue bar also.
I am playing on Kappa, and I talk to other players on Aim, but no-one else in my alliance has reported the same problem.
I have managed to log in on some occasions, and sometimes after logging in and doing some stuff, I log off and then cannot log in again. I suspect that it is user specific, for the following reasons:
1) I have tried with Chrome, Firefox and IE, and the only difference is that with ie, I can click on the menu items, but login does not complete. So one day when it was hanging on the blue bar, I tried to click "logout" on IE, and it logged me out. Then I started chrome, tried login, and
it logged me in. HOWEVER unfortunately this "trick" has not worked since, but there could be something strange with my account setup in Grepolis ...
2) My daughter plays on the same IP address, and today I could not log in as usual, but she managed to log in. I tried in the morning, tried with IE, tried with firefox, then gave up. She came in, I asked her to log in on her account (on chrome), and she logged in. After she logged out, I tried on her windows user but it hung again. I went back to my user, tried to log in, failed.
Strange thing today, I tried again just now with IE, and it succeeded. But it is running like a pig, soooo slow, I click and wait 10-15 seconds for a response to the click. Will log off and try again in a few mins ...
I have now managed to log in 3 times in the last week, and I am wasting my time and money playing this game. If this is not resolved pronto, I am giving up
which will be a shame, I started playing on 31st Dec 2010, and could not even log in one year later
I have tried all the things like clearing browser cache, cleaning up my PC, removing some unnecessary registry programs, etc, etc. I am not a PC expert, so there could be something I have not tried which will solve the problem, but I do not believe that it is PC specific as per item 2) above. However, the main differences between my daughter's account and mine are that she has only 3 cities while I have 70, and she is a standard player while I have administrator running. Maybe my account uses more memory? My PC is a couple of years old, but I hasten to add that nothing else on my PC has given me any problems, only Grepolis
which is also a shame as it was the most frequently played application until a few weeks ago (coincidentally when the update to 2.0 happened and paying became buggy and more of a pain than a pleasure ....).
