Hi Aaron,
If you're still having trouble, take your scope along to Astro Petes Telescopes & Cafe over in Palmdale Shopping Centre in Mt Gravatt. The guys there are very helpful and I'm sure they won't mind helping you out- they're pretty good that way. Saturday nights there open till late as they have their scopes out & do sidewalk astronomy there.

Regarding what Malcolm said about the dust cap maybe being left on- *face palm* we've all done it.
