All I Get Is Boxes...

i downloaded limewire and ran it succesfully for a day. after restarting my computer, whenever i started the program instead of text i would just get boxes...the program seems to be running fine but there is just no text...just symbols and boxes. so i uninstalled the program and reinstalled it and had the same problem. so i re-downloaded the installation file and re-installed it again to no avail! how can i get it to work again? it seems like something in windows must be corrupt because i re-downloaded the installation package...any help would be much appreciated!
