I keep getting an error when I try to delete text saying:

Serious Error From Xara Web Designer (in the top bar)
then...
Access violation exception at 0x00670CB5

You have the option to click "Continue" or "Quit"

If I click either one I get the following:

A serious error has occurred. A log of this error has been captured and can be sent to Xara to help improve Xara Web Designer. (etc... asks me if I want to send to xara) and it gives me a reference code which is:
bf373369-548f-43c1-9622-a19c572336d0

Someone please help! I need to edit my website asap to continue getting clients and it won't let me! I have tried restarting program and computer to no avail.
