Hi Amy, sorry to hear that you are having the same problem working with wpCentral and I hope that we can help.
Do you know if the website you created was set up using a multisite configuration or as a single instance? If you are using multisite then that might explain why there are some problems with Inspirations since it requires the ability to install plugins and themes to function properly, and this capacity is limited to the Network Admin account in multisite configurations.
I look forward to hearing back from you and please let us know if you have any other questions along the way.
