Start-Transcript Error: Transcription Has Already Started

I have code that uses start and stop transcript. Everytime i run the start-transcript  I recieve an error that reads "Transcription has already been started. Use the stop-transcript command to stop transcription. I have tried to suppress this error with no luck using -ErrorAction 'SilentlyContinue'. I am using v2.0 and running this from the windows scheduler

Start-Transcript -Path 'C\AMScriptLog.txt' -Append
#Code Here
Stop-Transcript
