uninstalling to fix avast

[system]

If i have to uninstall my paid ver of avast and then reinstall it to see if it fixes some problems, do i just need to insert the same license into the file again? How do i download the paid version again without paying for it. Also, is there an account to create or have with avast for users that pay for the program?
