Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, eg. uninstall Max's Pitch Package, etc. That can make things worse.
Before you post make sure you check the Help FAQ for an instant solution first. Then, if you can't find it there, you can post your problem here and we'll get to it ASAP (within 24 hours), but be sure you:
post in the right category
INCLUDE AT LEAST ONE SCREENCAP IN YOUR POST TO SHOW THE PROBLEM!!!!!!!!
explain the problem clearly
When I log in to Salesforce I get a different screen from my classmates and I got an email that maxlab has successfully been downloaded but it dosnet pop up for me. I asked my teacher about this and he is also confused on why I’m getting a different screen.
Looks like you got the wrong kind of account, alright. Did you not follow the link that Max gave on page 2 of Lab 1a to get your account? There her instructions say to be sure to use that link and NOT to go to the Salesforce website and get some other kind of account. They have lots of different kinds of accounts. It's super-important to read Max's instrucions and follow the carefully to make this all work, ok?
Let me know.
