Version 3.53 of the Studio is still silent in giving "usefull" error messages. An example is the "error in coff file" discussion with the ELFCOFF program. Is it possible to give more authoritve error messages, more details etc.? It is quite easy to make errors in the source code especially while mixing C & ass files in one project.
Also please do not delete the project from the last project list when there is an error in opening the project.
