Hi mason,

 

there was a very similar topic some days ago.

 

this is the only source code i have

I guess the lesson here is the same as in the other thread: use backups/SCC systems right from the start!

 

As a last resort you may attach your VI here or ask NI support for help…

Best regards,

Hi mason,

 

I get the same error "40" when tryin to open your VI.

Either get an older copy from a backup - or recreate this VI from scratch!

 

(It's rather big in terms of filesize. IMHO that is most often a sign of bad coding behaviours…)

Best regards,
GerdW
