Having trouble installing :( hoping for help

Hi there,

Well i have just discovered projectpier and thought i would install it and give it a whirl a community i belong to. I use a web host called zymic (yes its free and no i am not the greatest of fans) for doing this and have got it up there and have encountered a couple of expected hurdles. then i simply got the projectpier error saying it couldnt connect to the database.

anyway i followed the instructions and got the error message but im just not understanding it and was wondering if anyone could help

heres the message

Error (DBConnectError)
Failed to connect to database
