I cannot get a full 4,322KB (18 minute) recording to upload on Audacity 2.0.5. It only uploads 25 seconds of it. I am using Windows 8 and obtained Audacity by the zip. Please help ASAP!!!

also the recording was on a RAC RP5120-A digital voice recorder. Sorry i did not add that above.

Check that the Audacity temp folder is a valid location, is writeable and has enough free space.
