when implementing a design in M1.5 the following fatal_error occurs in map:
Fatal_error: baspm:c:190:1.21 dll open of lib4krt.dll
This applied to other dll files as well that produce the same error message.
This error indicates that the DLL file mentioned is incompatible with the rest of the installation. This may have been caused by a corruption of the file during installation, or the installation of an incompatible Service Pack or FTP Update file.
The solution is to re-install the software, making sure that any Service Packs used are compatible with the main release version.
