Help!!!

my limewire just up and decides to start over completely. this is the third time it's happened. i'll have some odd number of files downloaded and for example...about 5 minutes ago i clicked on the limewire icon and the setup installation thing came up as if i just had downloaded the software which is not the case. why in the hell is this happening. it's not that big of a deal i don't guess but it makes no sense.
