Hi Cathy.
Thank you for posting on the forum.
You should be able to reset all your default settings by loading up ActivInspire and clicking on File>Settings>Restore file associations.
Once you have done this, please close ActivInspire and relaunch, is the text toolbar still all the way across the top?
I hope this information helps, should you wish to get in touch directly with ourselves, I have created a support case to assist with this issue. Your reference number is 00427683.
