I can't sign onto AIM because a error message keeps popping up. Its says "Default Buddy List Doesn't Exist" and I rearrange my buddylist on my screename and still doesn't works. My friends signed in with their screename and was able log on but I can't with my screenames. I have a Voyager.
That would definitely be an error triggered by AIM, conflicting with the sign in attempt from your mobile. Best advice tomake sure your buddy list is set up properly via your home computer is to follow the step by step FAQs on http://www.aim.com.
If you have any buddy list groups with anything other then letters and numbers than you need to get on the aim on the computer and change it... I had a buddy list group named Extra S/ns so I had to get on to get rid of the /... hope this solves your problem
