I just downloaded NeoLemmix V12.0.1, and when converting my old NXP level packs to the new version with NXPConvert.exe, I gets the following error on the attachment.
How to solve the problem?
This error occurs whenever some graphic style piece is missing. Please download the rather large style zip from the NeoLemmix homepage (https://www.neolemmix.com/download.php?program=44) and extract it into your NeoLemmix folder. Then you should no longer get this error message.
PS: At the moment, extracting the style zip file will take quite long. Sorry about that - we are working on a better solution.
