Unable to copy objects on S3 - amazon-web-services

Question

I'm trying to copy video files from in my store from one folder to another. The files are all under 1GB. Everytime I try, I get an exception.
Name of S3 store: BandMedia
example files:
SourceFileName: VideoFiles/Band1/video1_38372836.mp4
DestinationFileName: VideoFiles/Band2/video1_47296110.mp4
The folder "VideoFiles" exist on my AWS S3 store.
However, the band name for the DestinationFileName is new(Band2).
So maybe it's not copying over because of that? Would I need to create the folder for the band first, and then do the copy? But I'm pretty sure I read in the SDK documentation that if the folder doesn't exist, it will be automatically created.
Here's the code that copied pretty much from the AWS SDK examples:
Try
Dim AppSettings As Specialized.NameValueCollection = System.Configuration.ConfigurationManager.AppSettings()
Dim AwsAccessKey As String = "xxxxxx"
Dim AwsSecretKey As String = "11111"
Dim AwsBucketName = "BandMedia"
Dim AwsRegionEndpoint As String = AwsEndPoint
Dim AwsRegionEndpointObj As RegionEndpoint = RegionEndpoint.GetBySystemName(AwsRegionEndpoint)
Dim s3 = New Amazon.S3.AmazonS3Client(AwsAccessKey, AwsSecretKey, AwsRegionEndpointObj)
Dim cRequest As CopyObjectRequest
Dim cReponse As CopyObjectResponse
cRequest = New CopyObjectRequest()
With cRequest
.SourceBucket = AwsBucketName
.DestinationBucket = AwsBucketName
.SourceKey = SourceFileName
.DestinationKey = DestinationFileName
.CannedACL = S3CannedACL.PublicRead
End With
cReponse = s3.CopyObject(cRequest)
Return cReponse.HttpStatusCode = 200
Catch ex As AmazonS3Exception
Return False
End Try
Here's the error:
Exception thrown: 'System.Exception' in videoMusicApp.dll Exception
while copying file VideoFiles/Band1/video1_38372836.mp4 to
VideoFiles/Band2/video1_47296110.mp4
Another thought...maybe it's because it's on the same store?
Honestly, I don't know though.
Could anyone help me out? Thanks!
