I'm glad you're up and running again!
I was going to come on today and offer you my code anyway, since its seems the CD version is no longer available commercially except for a few copies being sold by private sellers. More's the pity, since it is a nifty piece of software, IMHO.
I'm just about to start the Mephisto, and I always have the programme open to check the many obscure words I encounter.
I do use Chrome occasionally when IE is playing up,and I will have to in future for this site, as I too am having the missing letter problem, and its crashed both my home and works computers several times.
Good luck. Eddie aka GWA
