Installing Sabnzb fails - SSL issue

[nicovanl]

Hi, can you help me please?

Using CSI on my WinXP SP2, after successfully installing opkg on my A300, I am not able to install Sabnzb (In CSI, I select "SABnzb 0.7.1", press "next" and I get an error like "retrieving program failed").

The errorlog.csv file says:
..
