Overwrite of Trial Version working files upon full Version install.

I downloaded and used a trial version of Acrobate XI, having created and saved an number of files.  I have since then purchased the full version on disk.

1. Should I uninstall the Trial Version first before I attempt to install full version??

2. If so, how do I save the files that I created, so I can transfer to the full program version??

3. If I do not need to Uninstall the Trail Version; then upon full version install, will my saved files be AUTOMATICALLY be transfered / incorporated into the full version?

4. If not, how do I transfer files to the full version?

I am using HP Pavillion All-in-One with Windows 8.

Thx Much.....
