Are you sure that it's the length that is the problem and not something else?
What is the exact format they require?
Mono / Stereo?
VBR / CBR?
Bit rate?
Sample rate?

Not sure exactly what you mean It means, if you have a track that is, for example, 2 minutes long and you encode it as MP3, then the MP3 will be a little over 2 minutes long because encoding adds a bit of extra silence to the start of the file. If you need the track to be no more than 2 minutes, th...

It's a limitation of the MP3 format. MP3s always have a bit of padding at the start because the format does not define the overall encoder/decoder delay.

The maximum size for a normal WAV file is 4 GB https://en.wikipedia.org/wiki/WAV#Limitations
so either you need to use a different format, or split the project into multiple files.

Try exporting it in a more reasonable format, such as 16-bit, 44100 Hz.
To set the sample rate, select 44100 in the "project rate" box in the lower left corner of the main Audacity window.

It looks to me like data corruption. Possibly due to the flash media failing? The left channel shows severe damage, so I think the best thing you can do is to delete that channel and use the (good) right channel as a mono recording. A mono track will play through both speakers. From the track dropdo...

Before you launch Audacity, connect the USB device, then check in the Windows Sound Control Panel that the device is listed as an available recording device. If it isn't, try turning off your computer, check the USB lead is plugged in securely, then reboot the computer and check again in the Windows...

Perhaps you installed it into a different user account. If you install Audacity from the .exe (recommended), and accept the default options, Audacity should be available for all standard users (installing this way should be done from a standard user account and may require entering the admin passwor...

Yes, but PortAudio's 24 bit sample format is different from Audacity's int24Sample format, so Audacity makes PortAudio return float samples when recording in 24-bit samples. See AudioIO.cpp.

The best way to record Skype (or other voip) is to use software that is designed specifically for the job, such as Pamela for Skype.
