[Multi Encoder] - is corrupting files and throwing errors

[TonyPf]

After trying to convert WAV to FLAC and having about 300 discs where one or two WAV files on each of the albums throws errors with the following messages, I have narrowed this down to creating a [Multi Encoder] process where I wanted to do multiple steps in one process rather than running each one individually. The various errors I am getting are of the following types:

Error converting to [Multi Encoder], <path to my WAV file to be converted> to <path to where my FLAC file will be created>
Error Cannot Create Wave Decoder (Unknown ACM ID: 0 (ACM decoder not installed))? [clWaveDecoder_Wave::PrepareToDecodeAudio]

Error converting to [Multi Encoder], <path to my WAV file to be converted> to <path to where my FLAC file will be created>
Error Chunk is out of file. [clRIFFHandler::ScanFile]
Error Cannot Create Wave Decoder (Unknown ACM ID: 24932 (ACM decoder not installed))? [clWaveDecoder_Wave::PrepareToDecodeAudio]

Error converting to [Multi Encoder], <path to my WAV file to be converted> to <path to where my FLAC file will be created>
Error cannot find 'data' chunk. [clWaveDecoder_Wave::PullOutFMTnDATA]
Error cannot find 'data' chunk. [clWaveDecoder_Wave::PullOutFMTnDATA]
Error cannot find 'data' chunk. [clWaveDecoder_Wave::PullOutFMTnDATA]


Steps to generate the Errors:
If I run each of these steps individually, the WAV file(s) convert to FLAC without any errors:

1. Run against the folder with the WAV files: [FLAC]: Base Location is set to "G:\Music_FLAC" and Output To is set to: [TRIMFIRSTFOLDER][origpath][]\[origfilename]
2. Run against the folder with the FLAC files: [Tag From Filename]: Tag Recognition: [Album Artist]\[Album]\[Track] [Title] ==> If I view the Properties of the FLAC file and look at the "ID-Tag" tab, this sets the Title/Contributing Artists/Album/Album Artist all correctly
3. Run against the folder with the FLAC files: [Tag From Filename]: Tag Recognition: [Artist]\[Album]\[Track] [Title] ==> If I view the Properties of the FLAC file and look at the "ID-Tag" tab, nothing really different changed but was doing this as a test to get the ID-Tags sets correctly

Now, if I create a [Multi Encoder] with the exact same 3 steps I ran individually above on a Prince album, it errors out with the errors noted below

Anybody know why this is happening? Should I not be using a [Multi Encoder]? Or am I using it incorrectly? When it works, it works, but no idea why it fails on some of these and not on others.
