Audacity Forum

I was trying to record something, and decide to take a break, so I saved the project. I continue later, but when I try to open it, I get an error message saying: Reference to invalid character number at line 7. How can I fix this? ><

That error usually means that you used illegal characters in your project name, or in one of the metadata tags in the project.

You can open the project .aup file in a text editor such as Notepad.
In the Format menu in Notepad, turn off Word Wrap.
Now look at the seventh line. It should look something like this:
There will probably be some unusual character in the text between the quotes where I have written "whatever name you gave it"
Change that, so that it only uses a-z, A-Z, 0-9 and spaces, and it should open OK.

PO'L

Trouble with Notepad is that it does not show line numbers. (Notepad++ can show line numbers http://notepad-plus.sourceforge.net/uk/site.htm )
If you have trouble finding the line, copy and paste the first dozen lines in your reply.
