AIJ 5.4.2.00 Exception on File Import Image Sequence

[brandx]

Hi
I'm receiving this exception on File Import Image Sequence:
----------

File Open works ok but not for a set of data. ****UPDATE - now File Open receives similar exception***

Suggestions welcome!

Thanks, Les

After you select the folder of images you are attempting to import, what number shows next to "Matched files" near the bottom? If it is 0, AIJ is not seeing any compatible files in the folder.
