I'm using Pure ASP Upload on a website which has been in production since 2001 so I'm not sure which version of Pure ASP Upload I'm using but I guess it will be old. So as of today I get this:

You don't have latest version of ScriptLibrary/incPureUpload.asp uploaded on the server.
This library is required for the current page. It is fully backwards compatible so old pages will work as well.

In my opinion it doesn't matter if 20 new versions have been released. The old component should still work.
The site has been uploaded 6 years ago and nobody touched it.
So I wonder where this error comes from.
Could it be because of some upgrade on the webserver or whatever?
I can understand that a component does not work anymore on an server after 6 years due to changes in the environment but the site or the code itself has not been changed.

Anyone with an opinion?
Many thanks in advance

Steve
