If your file has sensitive content, when you choose Contact Omni, you can pick to Anonymize the file, which will replace all of the text with the letter x. It will help us test that every case is fixed if you are able to send us your file. Sorry for the trouble.
Thanks for the reply… I just tried to uni-install re-install and still have same problem. Moreover the error does not always pop-up when opening, but instead pops-up when I choose to duplicate, which effects my version control.
