So while i'm waiting for the pro version to be emailed to me.
If i install the free version, would it be possible to install pro version after and not loose file downloads etc.

As in any software, migration or upgrade is really tricky. On one hand, you will have a more advanced and up to date application but on the other, you would have to endure lots of time to back up, check and restore your files. Even if it also is from the same software laboratory, there still are some issues in between versions. Be sure to have your backup ready in case all fails.
