Perfei You had posted a screenshot of the invoice, but since it contained your personal information—such as the email address registered for the license—I have removed the image.
We are aware that the invoices we issue may display garbled text in some PDF readers. Since we generate our invoices with the fonts properly embedded in the PDF, we unfortunately cannot do much more to address this issue. However, since this is an issue limited to certain PDF readers, the invoices should display correctly when opened in a browser such as Google Chrome.
Even if the text appears garbled, the content itself should be displayed correctly. If you have software capable of editing PDFs (such as Adobe Acrobat), you can correct this by reapplying the fonts yourself.
