Failed to Load Dynamic Library

[blaffie]

I am using LabVIEW 2013 (SP1 - 32-bit).  I created a sub vi called trigger.vi during last week.  From the main VI I compiled an executable which works fine.  But now when I try to open the sub VI  file I receive the following message.

trigger.vi is my own file which I tried to open and the sub-vi's on which it depends is avaliable.  From the main VI this particular VI is shown as an "?" and I cannot replace it.  

Any suggestions?

Yes, this VI is damaged. I can not open it.

Does the question mark look like the one on the table of the next link?

It looks like Colin is probably right, this VI might be damaged, in wich case, I hope you still have a working copy of it.
