[Resolved by Porting Kit update 4.1.6] When you don’t have that version, then restart Porting Kit, it will then auto update.
[update] Problem found, new porting Kit update will be released in a few hours.
Here a quick heads up. If you experience an error: “ERROR: Cannot read property ‘downloads’ of undefined” while installing a specific port, then you may know we are working on it to resolve it. We hope for a fix for this issue asap and only a bunch of games are effected, so most games aren’t. If you experience the issue, then keep watch on this blog post, when it is resolved. We hope tomorrow and it may come with an update of Porting Kit. That update will also include some extra features which were already planned.
So keep a close watch on this blog post when it’s fixed when you experience this error.
