ERROR with NI Switch node

[CharlieCat]

Today, I was working with LabVIEW (v8) and suddenly from one another execution the niSwitch nodes stopped working at all (I didn't rewrite anything of that "part of the code"). The error looked like this:

(I tried restarting all the systems, only executing this VI... making a copy of this project and try again... the only thing i didn't try is to make a new project and copy the stuff i just need).

How many Switch device are you using? In my experience, called Initialize.vi in parallel caused similar trouble.

At that time, Call Library Function node said that it couldn't call specified DLL.

Yep, It was totally a problem of parallel switches. Thank you very much ^^
