I looked for the options.bsm file, and it does not exist, though there are several options.bak listed, all with modification dates from last year (even though I use beersmith weekly, and this problem started just a month or two ago). So I'm guessing that this missing file is the problem - so should I just change the name of the most recent backup to "options.bsm". Will this mess up any of my stored info?
I don't know what you mean by checking permissions. Do you mean for the "beersmith" folder? I went to "security" for that folder, and it appears that all permissions are enabled.
Finally, I'm not running for a removable drive, just my d: partition on my main hard drive. It's a fresh install of windows Vista.
