What Workbench version is it asking for?
Where are you located?
I see your website is NewTek.com ? VERY interesting. Hmmm !!
I can provide some help, if you answer those questions.
Have several test drives available on the bench right now.
I could prep a drive with the version you need, and you can test the system. If you want to keep the drive, then we'll have to discuss it.
The test drive is free, you pay shipping both ways, and a refundable security deposit.
Suggest you email me.
