Product upgrade

I installed trial version of VP UML professional.
Every time I start the product it provides an opportunity for upgrade.
When I try to update it’s looking for server address that I really don’t know. Please advise.

Dear Michael Belsky,

Thank you for your enquiry. I think that you are referring to “Manual Connection”. Please select Automatic Connection from the page where you are asked to enter a Server URL. Select one site to grab the updates. Any one would be fine. Of course, by choosing one that is close to you, you can gain benefit from the faster download speed/

If there are any further inquiry, please do not hesitate to contact me.

Best regards,
Jick Yeung
