This one's classic. I try to open a file that has been added to a project and I get the error message:

"Object reference is not set to an instance of an object"

What on earth is that supposed to mean?

And if the file have been prepared in Studio, why can't Studio open it? It makes no sense to me.

The full error message is:

Restarting solved it Dec 3, 2010

Interestingly enough, restarting Trados solved the problem. But that doesn't explain why it happened in the first, however. You should be able to add files to a project without having to restart the program.

Installation glitch? Dec 3, 2010

How are you trying to open the file?
Are you opening it from the Files view?
Have you just added the file to an existing project?
If so, you are probably in the Source-language view (Source language selected in the drop-down list on the left).
Make sure you switch to your Target Language first and then open the file.

"Object reference is not set to an instance of an object" is a generic error message.
The error log actually looks like there might be a problem with your installation. Have you tried reinstalling?

Source/Target language Dec 3, 2010

I've fallen into that source/target language problem before - so, no, it wasn't that. But even if it had been, the file should have opened.

What is it in the error log that indicates a duff installation (out of interest)? I'm loathe to reinstall software, if I don't have to. Especially bearing in mind it means redoing all the hotfixes and repairs and possibly losing all my settings.
