Πρόβλημα σύνδεσης με πλατφόρμα eLearning

Καλημέρα!
Έχω ένα πρόβλημα με την πλατφόρμα eLearning ενός κέντρου στο οποίο μαθαίνω ένα πρόγραμμα.
Συνοπτικά: κατεβάζεις από το site τους έναν player μέσω του οποίου κατεβάζεις το εκπαιδευτικό πρόγραμμα για το οποίο έχεις πληρώσει τα δίδακτρα, και συνδέεσαι με τα στοιχεία σου και τον κωδικό που σου δίνουν.
Όταν πάω να συνδεθώ μου βγαίνει ένα μήνυμα που σας επισυνάπτω (screenshot) και αν πατήσω continue δεν προχωράει παρακάτω για να βάλω τα στοιχεία μου. (εννοείται έχω κάνει πρώτα τα βασικά restart-uninstall και εκ νέου installatioon, έχω δοκιμάσει να συνδεθώ και από το wifi του σπιτιού, και από το data connection του κινητού μου με hotspot για να αποκλείσω το ενδεχόμενο να φταίει η σταθερή μου σύνδεση, έχω προσπαθήσει και με κλειστά antivirus & firewall, αλλά πάντα με το ίδιο αποτέλεσμα τελικά.) Τέλος, συμμαθητής μου ο οποίος έχει Windows 10 όπως κι εγώ, το τρέχει κανονικά, οπότε αποκλείω και θέμα ασυμβατότητας (έχοντας δοκιμάσει και διάφορα compatibility modes)
Παρακάτω αντιγράφω και το πλήρες μήνυμα που βγαίνει στο Details, μήπως μπορείτε να βρείτε κάποια άκρη:
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
