[ubuntu] Clip grab stopped working after a couple of weeks

view story

http://ubuntuforums.org – I was using clip grab for a couple of weeks, then all of a sudden it will not download files anymore. I insert a URL and it is as if clip grab does not recognize it and the file type options remain inactive. I tried googling the problem but it seems complicated to me. Can someone explain what went wrong and what I can do to make the program work again? Thanks. (Hardware)
