Problem opening a VI due to improper shutdown of PC.

Question

Hello,
I am using LABVIEW-7.
I am having problem in opening a vi
that i created and named as ‘P Calculator.vi’.
When I click on it, window (W1) opens
in which it searches for sub-vi. The search halts when it looks for
’Obsolete ni Switch.LLB’ and immediately, window (W2) opens
asking to find Vi named ‘p calculator.vi’. (Please refer to
‘Doc1.pdf’for the snapshot of my desktop screen.)
When I click on ‘P Calculator.vi’
which is there in the window and click on ‘open’, the same
window keeps popping up and keeps asking for locating ‘P
Calculator.vi’.
If I click on ‘cancel’ and wait for
a while, LABVIEW – 7 window opens and nothing happens further.
If i do not wait enough and use ‘browse
option’ for manually locating ‘Obsolete ni Switch.LLB’ through
the given path, a new window (W3) opens. (Please refer to the
‘Doc2.pdf’ for the snapshot of the desktop. )It again asks for VI
named ‘P Calculator.vi’
If I ‘cancel’ this window, again
LABVIEW-7 window opens and nothing happens further.
If I choose ‘Ignore this VI’ option
instead of ‘browse’, again LABVIEW-7 window opens and nothing
happens further.
I was able to open it normally until,
one day, after saving and closing it properly, before the main
Labview 7 window was closed, PC power got cut abruptly. Since then
this problem persist.
 Kindly advise me how to open this vi.
Thank you.
Regards.

hi there
the vi LV keeps asking for is corrupted. It exists as a file, but the bytes got muddled up so LV dosn't regocnize this file as a valid vi. Propably you have to use a backup copy of that vi.
