Activation window keeps popping up every time Draftsight is started

We just installed Draftsight on 3 new computers for some users.  Every time these users start up Draftsight, the Activation dialog box pops up and they fill out their e-mail and information and click Activate.  They do not get the usual notification screen saying that an e-mail was sent to them and to click on the link.  The Activation window just goes away and Draftsight is running.  Once they close, the process starts all over again.

I have looked through all the iQuestions posted on this site & the Istallation & Activation Blog and have tried all the recommendations (admin rights for users, safe mode, anti-virus off, checking junk mail, etc) but they have not worked.  I even did a complete uninstall of the software along with deleting anything related to DS from the C drive and deleting anything DS related from the registry.  That too did not work.

Is there something that I am doing wrong?  Is there anything else we can do to turn this annoying activation window off?

Any help would be greatly appreciated.

Thanks,

Chris Pemberton
