Hi Dave76. Again, thanks for your time, and sorry for not getting back earlier to you on your last post (it's been a busy week). I haven't come around to the hardware suggestions yet, but I will get to it next. In the meantime, here are the last messages that contain the "error" word on EventSys.txt. Some of them clearly don't look like errors, but I preferred to send them to you in case they are relevant. I hope the translation is good enough:
