I'm not sure how I could control that, I simply downloaded it from the website, and have done so several times all with the same result.

Okay ... another way of looking at it is to scroll down through the downloaded pdf before you save it. Only save after you can see the entire document fully populated. I apologise that I can't help beyond this.

If I had that option I would try, however I only get a download option, no choice to open first before saving.

If you are using Microsoft's Edge browser, a download dialogue box opens after you hit the Start Download button for VP14's manual on the support page of vegascreativesoftware.com's website. The dialogue box should have three options: Open, Save and Cancel. Rather than saving via the Save button, hit the Open button. This should then open the pdf file as a fully displayed document. If it is fully populated - i.e. no unintentional blank pages - save the pdf file via the 'save as' function in the pdf display in the header.

It might also be worthwhile checking to make sure that your pdf viewer (e.g. Adobe Acrobat Reader) is the current version and up-to-date.

Win 10 doesn't need acrobat (thank goodness!). Edge should be the default viewer unless overridden.

I downloaded the manual on my tablet and it worked as expected. Try rebooting and downloading to a different location, then open is Edge.

You are probably seeing blank pages as the browser is trying to open the document directly from the online location. If you make sure it is downloaded locally to your machine (probably by right clicking the link for the manual and selecting "Save link as..." or similar, pick a location to save it, and then once it is downloaded open that downloaded file directly, you should find that the manual opens and all of the pages appear.

The other possibility is that Edge or whatever you are viewing in is actually still rendering the document internally. This can take quite a time with larger files with more content as it seems to do it sequentially. If you switch to another window it might actually hold up the rendering process, so if you go to page and leave it for a few minutes you may find that the correct page appears.

I clicked "open" when promoted to in Edge and it didn't display until it was fully downloaded and I could scroll to any page w/o any issues.

Unless you've got a 15+ year old computer (or one REALLY bogged down with resources being used) you should have no issue viewing that PDF, there's nothing special about it.
