Hi,
When did you get that error - when you downloaded from Scribd?
There is an issue with getting the Universal Test Framework directly from SourceForge at the moment - and they are not being the quickest to help.
However, you don't need to go via the SourceForge download. If you get hold of the manual it will show you how to download directly via CVS. The video on my blog also takes you through these steps.
Get hold of the User Manual and all the instructions are there. I have heard of no issues with Scribd and I know others have downloaded it. Please try again.
The direct link is below:

The link on the blog is certainly OK at the moment.
You can run Ant from the command line - but you need to tell it where things live as I mentioned earlier.
Thanks for trying the UTF. Best of luck with your endeavours!
