Problem transferring projects+samples to Mk2

Has anybody had any luck fixing a problem where samples are missing after a project+sample transfer from Rytm Mk1 to Mk2? What happens exactly is I transfer all the samples using Transfer, and all the samples come across fine, then I use C6 to upload then download each project individually. But with each of the projects, a large % of user samples are just blank in the project even though the samples are in the Rytm (some user samples do get found, some don’t). I hear it’s something to do with the checksums of the files…

I’ve been in contact with Elektron support and they’ve been saying for 3 months that they’ll do this and do that and get back to me next week and every time they never do, it’s been back and forth, extremely painful customer service…

I can’t sell my Mk1 till I resolve this. The ‘manual’ option would take daaays to do, because not only do I have to go in and re-connect every sample individually, but I have to do it in the right order for every project so it would involve going into different sample folders in my drive over and over and over again.
