How Can We Help?
I/O error 103 The semaphore cannot be set again.
I am getting the error: Could not save the macro due to the following error: I/O error 103 The semaphore cannot be set again.
Most likely the macro (.mex) file has somehow become corrupted or is located in a place where you do not have write permissions. Try the following:
1. Click on the File | New Macro File and create a new macro (.mex) file.
2. Try creating a new macro and save. It should save correctly.
3. Import your existing macros from your old file. (File | Import | Import Macros).
