hi, 22259 is dsm 6.2 beta the latest available is 15152 (6.1.3) you can try to compile you modules with that but maybe its also useful to check the log first about the reason, maybe dsm 6.1.5 does not contain a module that was part of dsm before, can also be a change in source code and if thats the case and its not working with 15152 build modules the only thing is to stay with the last working dsm version until source is available   https://sourceforge.net/projects/dsgp
