Problem in creating invoices

Hello
I have seen threads relating my problem. I found your plugin with micro template exactly as per my requirement. I installed and it created ONE invoice perfectly, but before i decide to go for premium version it stopped working. ??
Please help me.
thanks
manu

As suggested I created a log as follows:

Fatal error: Uncaught exception ‘MpdfException’ with message ‘Can’t open file /home2/dhhcoin/public_html/vanajaorganics/wp-content/uploads/woocommerce-pdf-invoices/mpdf/ttfontdata/dejavusanscondensedB.GSUBGPOStables.dat’ in /home2/dhhcoin/public_html/vanajaorganics/wp-content/plugins/woocommerce-pdf-invoices/vendor/mpdf/mpdf/classes/otl.php:297 Stack trace: #0 /home2/dhhcoin/public_html/vanajaorganics/wp-content/plugins/woocommerce-pdf-invoices/vendor/mpdf/mpdf/mpdf.php(16211): otl->applyOTL(‘VANAJA ORGANICS’, 255) #1 /home2/dhhcoin/public_html/vanajaorganics/wp-content/plugins/woocommerce-pdf-invoices/vendor/mpdf/mpdf/mpdf.php(15104): mPDF->WriteHTML(‘<table class=”c…’, 4) #2 /home2/dhhcoin/public_html/vanajaorganics/wp-content/plugins/woocommerce-pdf-invoices/vendor/mpdf/mpdf/mpdf.php(14970): mPDF->_getHtmlHeight(‘<table class=”c…’) #3 /home2/dhhcoin/public_html/vanajaorganics/wp-content/plugins/woocommerce-pdf-invoices/includes/abstracts/abstract-document.php(183): mPDF->SetHTMLHeader(‘<table class=”c…’) #4 /home in /home2/dhhcoin/public_html/vanajaorganics/wp-content/plugins/woocommerce-pdf-invoices/vendor/mpdf/mpdf/classes/otl.php on line 297
