Is there a working DHL plug-in available?

Recently, we got an offer from DHL and we like to try offer DHL shipping for our intl, non-US customers.

I tried the plug-in below and it is not working.

I tried it with zc 1.57d. I'm able to fix the warning errors, but there is no quote showing up. It shown "We are unable to obtain a rate quote for DHL shipping." during the checkout page. It is possible since it is an 8-year old plug-in...

Anyone know, if there is a plug-in which can show the DHL quote to the customers?
