After I accepted the last upgrade of my Xara Web designer Premium (17), I am not able to edit my job. I got the next message: Access violation exception at 0x00007FF700104304, and if I click Continue, my job is loaded but can not do anything because I got the message: Internal program error 802.w.dll.gr

I am running Windows 10 x64

Please let me know what to do, because it is important for me to update my page. Thank you very much
