The only real crack for IDM is the Ali.dbg one. Rest usually don't get updated and cause issues, make sure to fully uninstall IDM before installing a new version (using: Bulk Crap Uninstaller, Revo Uninstaller, etc...)
Btw, Free Download Manager is something to consider, it's opensource, free, without any tracking/ads 🐂💩 (With integration for FireFox and Chrome or any browser based on these two.)
- never pay for a software that spends more time creating problems instead of improving their product.
