Can't import any build error ...nil value

[MayoFaro]

Hello, I have just installed PoB and cannot download any build. Each time, I get the same kind of message (see attachment) which tells me
Error in 'OnFrame':Modules/builds.lu:133:attempt to index field 'mainOutput' (a nil value).

I tried to change the access rights to the folders and subfolders, but to no avail.
I have no idea what to do.
Thanks for the advice and input.

You are on an old Version that has not been maintained for years, as you can see on the main page. The new PoB (for over 3 years already) is here: https://pathofbuilding.community/

Many thanks, Don't know how I've been that wrong. I think that being allowed to clik on "update" and seeing this version being updated confused me...
Anyway, thanks for the answer, hope the new version will work nicely!
