I am on MacBook Pro (4,1; early 2008) 2.4 GHz Intel Core 2 Duo with 4 GB RAM running OS 10.5.8 and using Switch 1.50 for Intel. I purchased Switch on 04 SEPT 2009, and have used it a little. It used to convert WMA to MP3 just fine. Now it does not. I thought I had corrupted a WMA file or something, but I have tried totally good, new files, and my experience is the same as that of "djv" -- it starts to convert, says it's saving a file, then the beachball shows up and the application crashes. I also uninstalled (with AppCleaner) and re-installed a newly downloaded version of Switch. Same problem.
Another strange thing is that WavePad (also purchased as the same time) also will not open WMA files. I get this message: "Error loading file. WavePad could not open the file [location and name] properly. It may be corrupted or an unsupported format."
I think maybe I was on OS 10.5.7 when I started using Switch/WavePad, and they worked on WMA files (I do NOT know for sure that I was using 10.5.7 then). Maybe something Apple changed affects this?
Please help us, NCH! Thank you!
