We've had a look at your files and they seem to be corrupted.
The first tell-tale sign is that the files are very small - just a few KiloBytes each.
The error message about your subscription is a red herring as we tried our best to open the corrupt file and mis-interpreted the bad data inside of it.
I can confirm that if you have been able to save a document in Stardraw, then you should be able to open it again, no matter what your subscription level was.
I would check your hard drive for errors, restore any backups you have and check your other folders for suspicously small files. David SnippStardraw.com Ltd
