I try to deploy and get access denied?

Hi,

I am at the last stages of completeing a large example I found on Enterprise Intergration Patterns with Biztalk and have already built and deployed a couple of the projects. But now when I try to deploy the last part I am getting 2 errors:

Error Unspecified exception: Access is denied.
Error Access is denied.

I have no idea why this is, i got it a couple of weeks ago on another example and then when I eventually emptied the event viewer it was fine, I tried this again but it isn't working now. I tried assigning the project a different strong name key from the other projects in the solution but this also makes no difference. It has been a couple of days since I worked on this but i don't know what could have caused this. Can someone please suggest why this happens and what settings etc. I should make sure are set?

I am running Biztalk 2004 on windows xp on a laptop.

Thanks,

Sharon
