activeX communication loss

[theboybatis]

I am running an 8.5vi, which controls a stepper motor using activX commands via a Phidget's card. Whenever any changes, however trivial, are made to the vi communication is lost, presumably due to something that happens when the vi is recompiled. The new and old vi's both work on other machines. This is presumably a problem with the computer and not labview so possibly not appropriate for the forum but I was wondering if anybody out there had experienced anything similar or had any ideas.

Hey Stephen,

I'm sorry to hear you're still having this problem.  Have you tried reinstalling the driver of the card? It could be that the DLL is corrupt.  

There is also a slim chance that LabVIEW did not install properly.  It might be an idea to reinstall it.  

Let me know how you get on with this problem.  

Regards,
