I've been using logos 4 fine until yesterday (2/24/17), I closed it and try to run the software to use it again. I found that i could no longer log in into Logos.com. I went online and try all the troubleshooting tips and nothing worked. I called tech support at Faithlife/Logos and as you might know they no longer support Logos4 and didn't offer any help whatsoever. I wish Logos wasn't so OS dependent, and it gets to be more like a web app, where it could run at any platform. Does any one knows if Logos.com blocked any Logos4 software from signing in? I ask so I will stop all my troubleshooting efforts if this is the case. I was able to logging in with Logos 6 on my laptop with windows 8, Android Tablets and cellphone. The reason why i still have Logos4 running with Windows XP at my desktop computer is because as I am still transitioning into having Windows 7 working at my desktop in another hard drive partition I am still having issues running some software programs including Logos 6 itself (Logos 6 runs very slow at the Windows 7 partition for some weird reason). In general I was very happy with my Logos 4 even with its limitations on features which exists in Logos 6 and wish it to keep working if my computer is working and I am fine with everything about it ( having windows xp ). Can any one help me please?
