Sorry about that. Could you please confirm if you can type symbols on other applications like Word or Notepad?
Also, I would like to inform you CS5 has been discontinued and is no longer compatible with today's operating systems. Any attempts to troubleshoot the install could result in it becoming unusable. We strongly recommend upgrading your software to a newer version that is supported. That way, we can provide you tech support and access to the latest updates and bug fixes. I apologize for the frustration. Please let me know if you have any questions.
