I'm running OK on Matrix. Of course I'm running Win10 after the recent crash of my rig.
Something has changed all right but because I'm on Win10 I'm able to get in.
Your still running Win7 I thought which is near end of life I think. Maybe they locked out all Win7 search engines but I don't know that for sure. Praying that's not true!
Good Luck my Friend! I pray you can get it sorted out. In the meantime if you need anything from Matrix let me know and I'll PM you on my e-mail.
Gods speed Mike!!
