If I could answere that question I would be beyond experiencing it my self.

When you get the solution let me know.

I was locking up during downloads and I thought buying Pro would resolve the problem but I was wrong! So, in that respect your no better off with the paid version.

Hopefully the developers will work this serious handicap out!
If so, I believe, it will do their business a lot of good.

Good luck resolving this issue
