Decode error! Invalid or unsupported TIF file

Hi,
I decided to edit IPTC data on my laptop using InrfanView (v.4.25) as I do not have IMatch installed but now I can’t view the edited images using IrfanView or PS on my PC.
IMatch shows the images as thumbnails. When trying to open the images I receive error messages like “Decode error! Invalid or unsupported TIF file (IrfanView) or File cannot be opened due to wrong type of file (PS).”
Can someone help me solve this issue?
I really appreciate any help.
