Pro Version – PDF download failure

Hi, i am sorry it is me again.

I needed the buy the pro version to change the font of my invoice.

However, the plugin don’t work anymore since I bought it..

I can preview my invoice. But when I click on “download” I have an error : “Network failure error” (but nothing is wrong with my network).

I get an error message when I scan my templates :

Ohhhh i found something, the invoice generation seems to be failing due this problem:
Error Message	fread(): read of 8192 bytes failed with errno=9 Bad file descriptor
Error Number	8
Error File	/home/approbiofz/www/wp-content/plugins/PDFInvoiceBuilder/vendor/phenx/php-font-lib/src/FontLib/BinaryStream.php
Error Line	147
Error Context	null

I had no issues with the free version.
