Sonic CD Burning software

Wondering if someone can help. I have a Sonic CD Burner on my pc. Was working fine for 6 months. I went to use it one day and now there is a problem. When I launch the software, The window is too large. I am unable to see all the choices on the left hand side of the window. I have completely wiped out the software from add/remove and from reg and rebooted. Same issue. Have changed display settings same issue. Any help would be appreciated.
