Audacity 2.0.2, MacOS 10.6.8 running on Mac Mini

I recorded some Christmas music from radio stream. All seemed well as I recorded it, and played it back. I saved it as an Audacity project so I could edit it into manageable size files for an mp3 CD (the projects each had about 24 hours of recording). When I later tried to open the project, I got two messages. The first said the project check found faulty sequence tags; the log file contained the following
12:41:59: Warning: Project check found file inconsistencies inspecting the loaded project data.
12:42:40: Warning: Track Audio Track had error reading clip values from project file.
12:42:40: Warning: Track Audio Track had error reading clip values from project file.

I told Audacity to repair the files. I then got a second message about ones about orphan blocks and asked if I wanted to delete them. Since it said they were small and doing no harm, I answered “continue without deleting”.

My project then opened but without any wave forms displayed on the time line.

What’s going on?

Audacity projects currently have a maximum size of about 13 hours when the sample rate is 44.1 kHz.

As it says in the Release Notes:

Headline issues
Large Projects

Projects with more than 2^31 samples (just over 13.5 hours at 44100 Hz) will not re-open correctly. Higher sample rates mean proportionally shorter times - so just over 6 hours at 96,000 Hz. We know the cause, and do intend to address this bug. Workaround: Before saving or closing the project, export to audio files of appropriate size, or cut and paste sections of audio containing less than 2^31 samples to new Audacity projects and save those.

Thanks. I suspected it was related to the length. That’ll teach me to read the instructions. :astonished:
