import problems

I am trying to import a cycling video, 1:20 hrs, which translates to 4 separate videos in the VIRB folder (3@3gb, 1@1gb)

The first video imported fine (this happened last time also) however when I try to import the others I get the 0/1 video import screen.

I have restarted VIRB (no luck) and laptop (no luck).

Removed card from VIRB and placed directly in laptop - no luck

I deleted the first (successful) import form the VIRB, hoping that this might resolve the problem, no luck

Renamed the second file and tried to import - no luck.

It appears that every file after the first is dead to me! this has happened more than once.

Any suggestions?
