Your comment is noted. Very sad to know you're coming across pirate copies on eBay. Anyone who thinks piracy doesn't exist on RISC OS, is living in cloud cuckoo land!
In reply to Peter Howkins:
As guestx has pointed out, the EULA should be consulted before installing the software. The external packaging itself can be opened, it's usually the CD wallet or envelope which has the actual seal on it, which you break if you agree to the EULA that's printed either on the envelope itself, or with the accompanying documentation.
It's pretty clear cut really. The EULA would usually have terms regarding whether the software actually works on your computer. This is where trial versions would usually come in, so you can have a good idea of whether it does work. A shame then that VA can't provide one. It could still function, but time out after 15 minutes or something?
