Code modules bust be loadable

Hi,

i get an error by starting my secquence the first time. 

The error Name: Code modules must be able to load.

I can eliminate the error when I unlock the button "log" for the Report.

After the unlocking i haven´t any Errors.

Now I lock the "log for Report" button again and try the sequence again. And now i haven´t any Errors, too.

I attached a file of an example subsequence where I have the error.

Can somebody help me why I get the error, and why I get the error just one time?

Kind Regards
