imaq avi get info do not retrieve any info

Hi everyone, 

I have some trouble with the vision VI IMAQ AVI get info, 

everything was working well then I don't know what happened but the VI does not retrieve any information on any files, and I get the following error:

Error -1074395993 occurred at IMAQ AVI Open

Possible reason(s):

IMAQ Vision: File I/O error.

I need the framerate, Width, height and number of frame from this VI or else I cannot develop my application.

it only returns 0 on all values but the number of frames which is not correct 4294967295

I am thinking I might have broken the vision library.

Thanks for your help.
