Trying to avoid a content filter at work?  I mean VPN isn't a dirty word.
How the heck did you expect anyone to reply without using it?

PPTP can be broken.  IIUC (and that's a definate *if*) the attacker
has to capture you logging into your vpn at least once, but more often
is better, and then can take home the packets and hammer on them at
his leisure to break your password.  AFAIK, once up, PPTP is secure.

On the other hand, pptp is usually simpler to set up than the alternatives.

I'm not sure how to troubleshoot this, each of those settings can be
valid in a different situation.  What you have to do is match what the
provider expects.

If the provider says you are not using the right auth method - what do
your logs indicate?  That would be a good place to start.
