i updated from version "i dont know, maybe 6.0012" to the newest one and of course i´ve got troubles with the def-file, so to say, there is nothing left from it.
first question, where is the cluster-feature?? while opening the def-file i´ve got 100 error-messages and all my clusters are gone.
second one is, how can i find out with which version a file was created?
As for finding out which version created the file, you can do that by opening up a GHX file into a text editor (ie Notepad, Wordpad). The GHX file is just a special xml file, so when you open it up they'll be a whole bunch of tags. One of the first chunks will be Archive version (don't worry about that one), and the next one after that should be Definition and then Plugin Version. Then you'll see Major, Minor, then Revision tags and the number of those represent the version...
