NOTE: I meant to post this in the Linux area. Steam update today, with I am guessing the new Beta, but it no longer loads the game. Update: After downloading the non-Steam version, and trying to run it, PA also fails with the following error: "./PA: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.17' not found (required by ./PA)" System specs: i7 980X Extreme cpu Geforce GTX 580 gpu (1.5 GiB) 24 GiB ram SSD (6 Gbps) Kubuntu Linux 12.04 LTS 64-bit Linux kernel 3.5.0-18-generic Xorg 11, version 1.11.3 Nvidia driver version 304.108 OpenGL version 4.3.0
This also reported as FS#2100. Also I'm checked Steam runtime and it's not contain required version of libstdc++
