Hi Marcos & The Whole ESET Team,
I want to apologize publicly for my snippy replies to this thread. Had a really bad week and both issues hit at the worst possible time. No excuse, I was wrong. I've been a happy ESET user for many years and I do understand the challenges you guys face with your software.
I re-installed again and played around with all settings and found disabling Advanced email client processing prevented the error and his plugin now works again. Was getting Access violation in module AladEL65.dll which is located in C:\Windows\SysWOW64\AladEL65.dll
Again, sorry for my unprofessional replies.
