New problem with VPHOT

I have a new problem with VPHOT

I have just uploaded 17 images of 2 separate targets. All uploaded easily and were processed. I have uploaded similar images before with no problems.

They all show up in my image list but when I click on all except the last one to be processed I get the following message:

Server Error in '/app' Application.
Could not find file 'E:\images\635680633858710000.fts'.

Interestingly I tried opening the files as they were processed in the image list and they were present. As soon as another image was added the previous one was no longer openable. The last image added can be opened as normal.

My internet is pretty slow so I don't want to try to upload them again. Have they actually disappeared or just hidden.

Cheers

Terry
