Ive been using T-Clock Redux v2.4.0 (beta 3, build 384) since Nov 27, 2015.
I just tried v2.4.1#414-beta portable, and this error popped upT-Clock 2010 (download)
I thought maybe the problem was I needed an executable...that possibly the previous 22.214.171.1244 install was an executable, not portable (couldn't remember for sure), but since I could not find an executable anywhere, I downloaded a second T-Clock Redux v2.4.0 (beta 3, build 384) portable today for comparison purposes.
Testing the second (portable) version of 126.96.36.1994 brings up the same error as version 2.4.1. Also, the Clock64.exe from the original 2.4.0 Ive been successfully using is 235 kb. The Clock64.exe from the second download of v2.4.0 is only 208kb, although the mouseover from both shows 188.8.131.524
