My ISP (Telewest Blueyonder - www.blueyonder.co.uk) has recently migrated it's web page servers from WinNT to Unix. Whereas my 3D content appeared when my ISP was NT (despite the water mark problem) it now fails to display at all now that their servers are Unix. Blueyonder tech support is baffled. Could anyone shine a light on this?

Did you register VET's files as MIME types on the new servers?

This might be a stupid question, but you know that paths & URLs are case-sensitive on Unix boxes, right?

Yes, case sensitivity is a crucial issue too! You should verify that cases aren't causing problems.
