buongiorno ho già una licenza Video DownloadHelper 7.6.6 Dear polvere gerardo, Thank you for purchasing the DownloadHelper Video Conversion License for Firefox. Your personal registration code is: 56b68b67144d4e879e1a8efa6787d0a2 If you purchased this license from the browser you intend to use it on, it should already be registered and you should be able to use the product immediately. Otherwise, or if you want to reinstall your license in your browser, open Video DownloadHelper settings, licensing section and copy / paste (CTRL+V) your license key, 56b68b67144d4e879e1a8efa6787d0a2 , to the dedicated area. You can access your invoice at https://www.downloadhelper.net/show-invoice?invoice=00336179&key=86b02570075bb19b535c07c42de57cae ma non trovo la pagina per inserirla non vorrei ripagare ancora una volta la licenza solo per aver reistallato firefox che mi si bloccava di continuo attendo vostre notizie grazie
