Can't open any WAAPI Tool

Question

All is in the question. Everytime I click on one WAAPI Tool nothing starts... :/ 

I've already checked:
-Connecting via a Python script works fine (tested with WaapiClient), so WAAPI is not completely broken.
-Ports 8080 and 8090 are open, but Wwise shows the following errors:
WAMP server failed to start (port 8080), will retry every 10s.
HTTP server failed to start (port 8090), will retry every 10s.
-I've tried changing the ports, disabling the firewall, and restarting Wwise, but the issue persists.
-Wwise.exe is listening on port 8080 (netstat confirms that Wwise is using this port).

Hello Arthur, this can happen when you have multiple instances of Wwise open. Only the first instance will succeed in listening to the port. Have you tried rebooting?

Thanks!
