ahright, sorry, quickfix:
open your .v4p in a text-editor and in the first line where it says
<!DOCTYPE PATCH SYSTEM "https://vvvv.org/versions/vvvv50alpha34.106.dtd" >
replace the "https" with "http" and save the patch to have it working again.
explanation: a few weeks ago one of the alphas did write patches with "https" which caused those problems, so we reverted that change.
