when i try to log in, it keeps attempting to contact server
This has also happened to me. (Mac OSX 10.6.8 on a 2.4GHz mid-2010 MacBook Core 2 Duo) I tried registering here, using my Web-Browser, and THEN opening Zatikon (since registering from Zatikon did not work), but I still just get "Attempting to contact Server". (I am in North America and this was occuring around noon on a Week-Day.) I'll be deleting Zatikon.
This is caused by a bug that locks up the server. We have not been able to find it yet but resetting the server fixes the immediate issues. If you notice that you can't log in please contact support so we can fix it.
