Update an ocmod.xml get error.

Hi all,

I have an extension for a live chat and I want to extend it with some few more codes.
I have modified the filename.ocmod.xml file and when I want to update and reupload the ocmod file, but i get error that the file have an existing ID.

Is there any docs what I need to do? <version>1.02</version> have been updated, but I think the code is the issue.
But if I change the code, is duplicate it and I feel is not OK.

You cannot update an existing ocmod!

First remove the old one, then install the new file.
Don't forget to refresh modifications.

OK, tx. Hope in the future we can also write update modules. How can in this way now to be updated a modul installed via OCMOD? The only way to delete and reinstall? Will not lose settings?
