Hi Laura, 

Have you also updated your Hub and Driver?  
You shouldn’t normally have to , but in this case I would recommend getting everything on the latest version. 
You can find the latest ActivDriver and Hub upgrade instructions on our Knowledge Base, separate links below: 

Hub Firmware Upgrade
Driver Update

Alternatively, please don’t hesitate to call our Tech Support and they can talk you through and do further troubleshooting with you. 
Your reference is : 00465055

EDIT:  Sorry, one thing I forgot to mention:  before you do all this, make sure your target devices in ActivInspire are still set to ActivExpression devices and not Activotes!
