OK, I have read a post on this before, and I have tried turning off the signing (click one manifest & assembly)
But that didn't helped, I am currently getting this error:
There is no editor available for 'C:\<path to .vb file>'
Please make sure the application for the file type (.vb) is installed.
Could someone please explain to me how to fix this error I am currently using Visual Studio 2005 Team Suite.

This happened to me today, too. It actually had nothing to do with the forms.
My machine would not load forms in a vb2003 upgraded project, but other machines could load the same project. The same forms would load fine in a fresh vb2005 project, so the problem was with the project, not the form itself.
It turned out to be a missing COM reference. The project referenced a COM library that was not installed on my machine.
This may not be the cause of your problem, but it indicates that the error "no editor available" message may be misleading.

Looks like the VB extension didn't get registered correctly.
Can you try to repair the VS install
