CorelDraw X7 save error a huge problem - what version should I upgrade to?

Unfortunately, I bought a three pack of this program before I found out you can't repeatedly save your work if you are using a cloud file system like Dropbox or Google drive. Since I travel and need to save to the cloud so my staff and see my work, this is an absolute no-go issue for this software. I must be able to repeatedly save my work. I figured they might have had a patch for it by now, but apparently that never happened. So, my question is this:

What is the most recent version of CorelDraw that does NOT have the saving error when you are saving to a cloud service? 

I have to buy this for three computers, so it's important to me that I get something that's going to work this time. Really upset that I wasted my money on this version before finding out it had this major flaw. I assumed it would behave like X5 only with more stuff.

Thanks for your help!
