I've just installed the plugin and I will be testing it for the following hours/days.
The first thing I could see is that the Romanian translation is totally wrong. Please remove it as it is impossible to understand what it's written there.
If the .po files are in the distribution, I'll try to make a human translation and somehow send it to you. If not, please send an email from drumliber.ro contact page (menu is on top), you'll figure it out :D
