How to change SmartGit's licensing option after 30 days of commercial use on ubuntu?

while installing smartgit 3.0.4 I checked the commercial licensing option, because I was just clicking "next" button : ) (30 day trial and then you have to buy it). Now today is my 31st day of using SG and I can't change my licensing options (reinstalling smartgit doesn't help) and I'm not able to use SG anymore without paying (I'm not using it for commercial purposes). Do you know how to fix it?

I don't have these files on my ubuntu: http://www.syntevo.com/smartgit/documentation.html?page=installation

I went on the internet and I found this:

To alter the license. First, go to

Windows: %APPDATA%\syntevo\SmartGit<main-smartgit-version>

Windows portable: SmartGit\.settings\preferences.yml

OS X: ~/Library/Preferences/SmartGit/<main-smartgit-version>

Unix/Linux: ~/.smartgit/<main-smartgit-version>

and remove the file settings.xml.

If you have updated many times, you may need to remove the updates folder as well.

It helped me on Windows, hope it helps you on other systems as well.

Starting from version 19.1 they have renamed filenames:

➜ SmartGit grep -rl 'listx' ./19.1
./19.1/preferences.yml
./19.1/.backup/preferences.yml

It is possible to delete them to reset the license setting.
