Can't connect to MacPro (OS X 10.7.5 Lion)

[SamAndrew27]

I'm trying to connect from my MacPro at home from a PC. Everytime I get "authentication failed" because TeamViewer says the password is wrong (but it's not). Here is what I've tried so far:

- Resetting the TM password
- Changing TM password to be the same as Mac sudo password and the same as Mac VNC "control this computer" password
- Disabling/enabling VNC screen sharing in OS X. Disabling/enabling remote management in OS X.
- Connecting (from PC) with "advanced options"

Nothing helps. Any ideas?? Thanks in advance.
