Limewire wont come up
 

My LW has been acting weird as of today. I double click the LM icon, and the "Upgrade to PRO" box opens up in the upper left hand corner of my screen. Normally, my LM automatically pops up, but it wont. Also, the LM tab is visible at the bottom, but when I click on it, nothing happens. Does anyone know why it wont come up? I've uninstalled, and then reinstalled three times. I'm not sure whats going on. I'm apologizing ahead of time if a similar thread has been posted. I've done some research, and couldn't find any that fit my problem. Thank you so much.
