cutt3r,
We need a little more information to recreate the problem you are having.
Which library are you trying to upload to?
The IconPackager library will only accept .ip and .zip file extensions. The ObjectDock library will accept .dockzip, .zip and a number of other extensions. None of the libraries accept .doczip as you have indicated above (note the spelling).
Please also note that the preview image must be .jpg as indicated on the upload page.
If the file extension is what the problem turns out to be, just remember to upload files with the indicated file extension that is given on the upload page.
