AAhh, limeiwre 4.14.10 help!!!(problems with mouse clicking)

When I double click on limewire it comes up properly but when I get the box that says do you want limewire pro, I cant x it out or click on later or anything. But when I click on another screen then click the x it will x out. But then the tip thing pops up and I need to do the same thing. But when all the boxes are gone, I cant click on anything in LimeWire. so I press ctrl+alt+del to close out limewire, and I have downloaded limwire multiple times and it keeps on happing. And yes I have turned off and on my computer and I have XP

PLEASE HELP!
