I requested the 4.1 installer this morning from Celemony and they sent it to me (and asked me to not distribute it)...
here was Ulf's comment about 4.2:
"thanks for your mail. There are indeed a few systems that have an issue with Cakewalk by Bandlab and Melodyne. We’re still investigating this.
However, the workaround is simply:
If you come across undetected blobs, simply select all blobs and manually chose the algorithm desired. This should do it for the rest of your session."
