SharePoint Application Page - File not found exception

I am developing a webpart in Visual Studio 2005 for SharePoint using a wspbuilder project template.

I deploy my pages,images,css and javascript files using WSPBuilder. Sometimes, I come across 'File not found' exception when I make a deploy using wspbuilder.

After some series of repetitive deploys, the page would work fine. I don't know what is the reason behind this. I am also including the stack trace of the exception which I got in the SharePoint Application Page.

make sure your application page references the full assembly name, including version and public key token in its Page declaration
