Thanks for the Reply Ernielive,
I installed Firefox and it let me access a differnet part of the Adobe site and download the flash player manually.
It seems Windows 8's IE10 is linked to accessing a different download menu on the Adobe site.
Installed Flash and it seems to be working now, Procaster is linking to the correct flash player file now, so Chat, Promote, and Player tabs are now working.
Thanks for your help!
