3shape model builder 2019 software removable die issues

Trying to print dental models for crowns with formlabs 3B and model resin in beige. Won’t work. Die is too tight and won’t fit. Also, not perfectly straight. I’ve tried multiples times printing on the build platform and with full rafts as well. Didn’t work… Any tips? I am using 3shape software and software 2019 model builder . I am also using the new DME files from formlabs and is still not working correctly
