after upgrading to win 8.1 pro it has stopped working.
Hi Latoungam - and welcome to the forums
And sorry to hear you are having problems.
Did you upgrade to 8.1 Pro from the 8.0 shipping release or from an 8.1 pre-release version?
When you say Logos has stopped working what exactly do you mean? Please provide some more details
Also, please enable diagnostic logging and upload logs after Logos has stopped working. Details at https://www.logos.com/support/logos5/windows/problem
