Forgive me if this is something that's been addressed previously; I did do a couple of searches but not found a thread with a suitable answer.

My problem has been that in the last few days I've not been able to open any of my existing .web files. Web Designer Premium launches but during the process just hangs at 99%. I'm not able to go any further. I then click in the program main window and Windows throws up the "Close program / Wait for response" dialog box. I close the program. I then try again and I may actually get as far as the "Tip of the day" dialog box, but after I click 'close', the same thing happens. Nothing. The progress bar shows 99%.

I'm wondering whether to just re-install WD but I'm not using the latest version and I've not renewed/upgraded to the latest version so not sure if re-installing would wipe the various components/pages I've also downloaded since purchasing WD?
(Note: I purchased the program in June 2017 (XWD Premium 12, 64-bit, plus backup CD), expired in June 2018, but the program has fulfilled my needs up to now. I had intended to eventually upgrade to the latest version but am not sure now given my current problems. I've also downloaded).

Happy to give more info if required but any ideas / suggestions would be much appreciated.
