The above listed line worked on my computer until last week. I'm now
getting this error:

Run-time error '-2147022794 (80070836)':

Automation error
The workstation driver is not installed

OK, what do I need to do to fix it. I've recently had to reboot my system,
so I'm sure I've had changes here in the last week. Any ideas?

Thanks,

Barb Reinhardt
