I have finished with my project on my Laptop and copied the project to a new desktop. Since then i am unable to make changes to my project. In other words, whenever i change codes or controls in my forms i dont get to see the changes made while debugging. Even when i place a breakpoint on any line i get the following meassage:

The brekpoint will not currently be hit. No executable code is associated with this line.
And once i got this message:

No source code file found.
I dont understand why is this happening and i am very scared about it.

Please somebody help.
