Microsoft's latest Windows 10 update appeared last night (presumably to address Spectre and Meltdown). My system seems to be working fine, and I can access my CD (well, Blu-Ray) drive via File Explorer, but when I start AoE in Single Player mode, the game tells me I must insert a game CD. It's in the drive and has never presented a problem before. Any suggestions (other than buying Definitive Edition if/when it's released next month)? Thanks.
