I updated two files this morning (one was readme.txt and unfortunately I can't remember the other file). After relaunching Sokoban I get a message:
This application has failed to start because dbrtl100.bpl was not found. Re-installing the application may fix this problem.
I have uninstalled/redownloaded Soko23b8.msi three times and still I get the same message. I have also use the 'repair' option and have received the same message.
Using the direction in the prior post -- download this file: "http://www.sourcecode.se/sokoban/download/vcl100.bpl" and have changed vcl100.bpl to dbrtl100.bpl but that brings me to the download page and not a file download.
What to do? I think I may uninstall again and reinstall the earlier Soko23b7.msi which I still have on my HD.
Thank you for the help Bjorn.
