What's happening to my limewire? Help, PLZ!!!!

[Walking_Contradiction]

Something very weird happened to limewire last night. I am using 4.12.6.(basic)
This is what happened. I loaded limewire to download a new song, while typing the name into the search box, limewire shut itself down and automatically downloaded its new version, 4.14.10, I do not know if it is Pro or not, and if it is, I am not able to pay. I did not click anything for this to happen. Why did it do this? I can't even load ANY of them now... whenever i try, I get a weird message from Java. Can someone please tell me whaat's going on... and possiably how to fix it? Will a system restore on the computer help?
