VRM: VEConfigure file with ESS assistant not updated on MultiPlus II

Dear all,
After being able to updload the changed VEConfigure settings file (change is adding e.g. the ESS assistant) the upload finally was fulfilled with no error messages.
Nevertheless in the Remote Console of the CerboGX I have no ESS assistant available.
Is there another way of uploading an assistant?
Or is there a way to get logfiles to see what is going wrong?

Thank you in advance!
