Whatever you had on your laptop before the clean up, probably long since expired. Those Adobe tryout have a 30 days expiration period. And Adobe allows for one tryout version for a given version. Add to that the fact that Adobe offers only the current version for tryout, and the current version is 13. If history repeats itself, Adobe will be releasing a new version in September October 2015 at which time that version will be the only one offered for tryout.
All that being said, you could try to download and install a Premiere Elements 11 tryout from the following web site....no guarantees....
But, if you decide to buy to get rid of the Adobe watermark from the tryout projects, you will need to find an authorized reseller who still has that version in stock.
Please review and consider. Any questions, please do not hesitate to ask.
