b4a bridge error?

After several months of faultless operation, I have a problem which I think lies with the connection of b4a bridge. One of my programs gives all the usual messages when being compiled, but the tablet shows a message box saying "unfortunately program123 has stopped". All of my other programs compile correctly. I have included a copy of the log file. Can anyone help as I am in an area way out of my knowledge?

Thanks
Charles
