I purchased the professional version recently and came across the exact same problem, along with a load of other script error issues realting to the same problem. After a frustrating day of closing the program and reopening it every time i wanted to run the bot, I decided on reading various forums and found that many others were having the same problem, so I set about finding a solution myself. I'm pleased to inform you all that I've found a work around that solves the issue. (Very occasionally the error reocurres briefly) The problem is 100% with the ubot software and the way it uses
