one of them is that your internet is acting wackyy. my wireless gets messed up for a while and signs me off too, so just try making sure that your internet is working properly. my usual problem is that the antenna fell or something simple like that.
the next thing i would suggest is, in the five minutes that you CAN stay online, go to "my aim" at the top of your buddy list, go to "save buddy list..." and save all your settings somewhere in my documents, or somewhere that you know where it is. then, uninstall and reinstal aim and then you'll notice everything is all messed up. so just go to "my aim" - "load buddy list..." and find the file that you saved all your settings in, and just load that. it will turn up JUST like you had your buddy list before you uninstalled :] even your profile.
