Error Importing

Hello, I’m having a problem opening my .aup files
I’m using Windows 7 64-bit and I installed Audacity from the .exe installer
Whenever I try to open the .aup file I get the “Error Importing” warning which says audacity can not recognize this file.
I installed the optional FFmpeg library on to my computer but I still can not open it
I have been using Audacity for a long and I have never encountered this problem before.
I regularly use audacity to record vocals and instruments for my music, however today I used a different method of recording.
Basically what I did on Audacity was import an .mp3 file in a stereo channel into Audacity and I recorded vocals in mono channels.
I set the microphone to the mic I was recording with and the speakers to the computer, so I could plug headphones in and listen to the music as I was recording.
Usually I don’t import .mp3 files and I set the speakers to the same channel as the mic. I listen to the .mp3 file on a separate media player
After I finished recording, I saved the vocals in mono channels with the .mp3 file which was in a stereo channel as an .aup file.
This is all that I did, I have no idea what is the source of my problem. I still have the data and the .aup files.

Please help, this is a huge problem for me.

Also when I open the .aup files and get the “Error Importing” warning, Audacity recommends importing it as raw data.
I have tried importing raw data from the _data folders and I have been able to import some raw .au files! (I did not compress any of my files, I just saved them as .aup)
However it will only import smoothly if the raw data’s settings are automatically set as
Encoding: 32 bit float, Byte order: Little-endian, Channels: 1 Channel (Mono), Start offset: 0 bytes, Amount to import: 100%, Sample Rate, 44100 Hz.
However it will not import smoothly if the raw data’s settings are automatically set as
Encoding: Signed 16 bit PCM, Byte order: Little-endian, Channels: 2 Channel (Stereo), Start offset: 0 bytes, Amount to import: 100%, Sample Rate, 44100 Hz.
If try to change the settings to match the first one, the audio does not import smoothly.
I have gone through the raw data for one of the .aup files and I have managed to recover some vocal recordings but I am still missing a lot
Most of the raw data can be imported smoothly is the .mp3 file’s data, which I don’t need.
I hope this information can help deduce the problem.
Also I have no idea what those settings mean haha

Are you using File > Open? Audacity cannot open AUP project files using File > Import > Audio (AUP files are not audio files).

Importing AU files is strongly discouraged unless you do not have the AUP file any longer. If you want to import an AU file, use File > Import > Audio, not File > Import > Raw Data which might give a click at the start of the file where the header information is.
