If you experience an issue with UVPackmaster, first read the troubleshooting pages of the products - they contain simple solutions to the most common problems:
If your problem is not listed there, feel free to write to us at firstname.lastname@example.org. If your question concerns a non-free product, then make sure you write from the e-mail address you used to make the purchase.
In order to speed up the troubleshooting process, it is recommended that you also send us a file (*.blend or *.max) with a UV map allowing to reproduce the issue. We understand that sometimes you don’t want to share your 3D models, in such case please consider scaling all 3D geometry in the file to a single point, so only the UV map stores meaningful data.
