Hi Jan Changes have been made to the Refmac interface in 6.1.1 which are not backwardly compatible. This means that if you try to rerun an old refmac job, it will give the error you see. The solution is to run a new refmac job and fill in the input fields from scratch.

This initially only happened in a linux installation, now all of a sudden appeared in a osx installation as well. The interface hangs when starting the job. It also occurs for files that refined w/o any problems before. Any ideas what is going on here? Thanks for any input.
