Viewpoint 3 - Image file cannot be loaded

I have a new install of Viewpoint 3 and it refuses to open any image file. I get the error “image file cannot be loaded”. This happens with all cases - when i use VP3 standalone and browse to a JPG, also when I export from Lightroom directly to VP3. The only place i can get VP to work is via Photolab 3. I have tried JPG and TIFF, and have also tried different resolutions and colour spaces on my RGB files. Have tried uninstalling and re-installing latest version and ensured it is latest updated version.

Anyone else had an issue like this? Hope someone can help.
