Unable to open anotated files

The annotation done cannot open on my HP. don’t know if I touched something.

Hello, I’m afraid a bit more information is required in order for anyone to be able to help.
Are there any error messages? Are there, after opening, messages in the log (View->View Log…) that seem to indicate a problem with either the annotation file or the media file(s)?
If you run File->Validate EAF File… on that annotation file, does it report errors?

Glad to say the problem has now been solved. I was just getting a grip of Elan then. tnx.
