Error importing from XMLTV "PVSGuideDataProcessor"

[Webbo]

After downgrading from 3.5.1 to 3.5 due to an issue with recordings now showing correctly in the guide.

The XMLTV importer runs correctly and launches the BTV import process, however this fails with the following entries in the log:

[12/6/2004 12:05:44] Guide Update started.

The real problem seems to be with "failed to create PVSGuideDataProcessor object: 0x80040154".

Has anyone else every encountered this? Any help much appreciated.

Gave up on this one and did a clean install of 3.5.1 and all appears well.
