How can I contiunue learning - java help on CodeGym

I'm actually at level 3, lesson 1, with IntelliJ installed and I tried to solve the task in that lesson - but when I'm trying to verify my code (in a browser), the buttons just goes grey and nothing happens. Moreover, lesson 2 of this level, where I installed the CodeGym plug-in - there are only tasks up to level 1, lesson 8 in IntelliJ (those wich were translated into polish - I would be glad to lear in english, but didn't figure out how to change lessons display language, however, I can't run any of the tasks because of the "uknown error" being displayed). And finally, on level 3 lesson 3 there is nothing to rewrite in the first task, and other tasks behave as the one from level 3, lesson 1. I would be happy to repay Your hard work that You put into designing this course and go forward, but I have to be sure that subscribing the CodeGym would solve the problem and make other levels and lessons to appear in IntelliJ. I attach as follows: - Level 3 lesson 1 task can't be verified:

- Level 3 lesson 2 IntelliJ issues and the error description:

useful

#1 If you haven't subscribed then the tasks won't be available. #2 to change your language there is a drop down menu way at the bottom of the webpage #3 While I can't answer most of your post on what will be available and not if you subscribe, there is a FAQ (also found at the bottom) that may have answers for you .

Thanks for answer. Unfortunately interface language changes only the interface, not lessons. I found solution: deleting "pl." from url. But those lessons are far away behind me.

However, I can't unlock the lesson, because it says:

Guadalupe Gagnon, You said: #1 If you haven't subscribed then the tasks won't be available. They're available, they just don't work properly. They're not "locked", there is no "premium" plate on them, I can open them:

My biggest concern now, but should be the concern of site owners, is "How did I reach level 3 without subscription?" and why any previous task was shown as available instead of beeing locked for premium user.

I see someone else from Tarnow is an the "Unkown Error" on tasks, probably they are working out bugs/kinks from the polish implementation. I wish I could be of more assistance, but I'm just a student here and don't work for codegym. The website as a learning resource, in my opinion, is great, but obviously if it isn't working properly in your country/language then spending money wouldn't make any sense.
