convert source code from vb6 to vb 2005 exp

I have a small project that was developed for me. The developer used vb6 although he was asked to use vb 2005 express. I have the code file that he sent me but am unable to open it with my IDE VB 2005 Express. I would like to email the file to someone who workes with VB 2005 Express and VB that can convert this work to VB 2005 Express so that i can load it in my IDE and work with it.
