Cannot view text when opening Captivate file

Hello,

I created a file last month and it worked very well.

This week when I opened it, all the text content disappeared, like transparent.

There are 40 slides and I inserted a video to the project last week.

At first I worked well and I was also be able to published it.

But now it's not working...and it always shows "Publish faliure".

Any idea?

Thank you!!
