Thank you so much for your quick response! I just wanted to let you know what has happened since I last wrote –
Yahoo has agreed to give me a refund because their brilliant and highly technical solution (re-installing the game) didn’t work.
I am working on resolving the sound card update with some technical assistance.
I don’t know if this has anything whatsoever to do with the problems I have been having, but I did notice that the error always occurs at the same time during the game (at least the way I’ve been playing it!) - in April 2007. I turned off all the sound options and the error still occurs. I tried to avoid all of the music-related options (disco, jazz concert, etc.) but even that didn’t help. The last error message popped up after I clicked the alarm clock to proceed to May 2007!
Once I get my refund from Yahoo I intend to purchase the program through your website! One last question from a non-technical person: are the downloads and updates for your version of the game easy to install?
