Oh damn, I totally missed those posts from November, sorry about not replying and thanks to milkshake for helping out. I totally should add some more hints or a general help to the program, I get that not everything is obvious to a new user. In fact (and to give this bump some sense) I am working on that right now: This is an integrated helper utility to guide the user trough the process of creating a PXML file. (SteaK's PNDCreator has something similar) It supports most of the PXML specification and probably all that is needed for 90% of the PNDs (things like multi-app PNDs, multiple categories, etc. are not implemented, but can be added manually with the already present PXML editor). I try to make it as easy as possible for the user to create a valid PXML file, so you have got some license presets (but you can add your own), sub-categories are filtered by main category (so you can't enter Game->WebBrowser any more), icon and screenshots show up as thumbnails, you can link to your executable directly through the PND browser (where you add files), etc. At the end there will be a short validation process to make sure everything is valid. Hopefully that will help new users get into PND business and also aide veteran developers, who are tired of having to edit the PXML file manually every time. Anyway, it's a work in progress, especially the final file creation is not done yet and I am currently rather busy so the next release will take a while. I also changed my setting to receive notifications when someone replies to this thread, so hopefully I don't miss any new bug reports. Cheers, foxblock EDIT: Well you can do that, in fact I use PNDTools to update my PNDs, too. I just open the old PND with the tool, replace file that have changed (or add new ones), use the integrated PXML editor to advance the version number and pack it again - works fine for me (Granted you use the most recent beta version, which you should btw, it's pretty stable and has this nice PXML editor).
