cant update from older version 1.0.0.00 to current

i get an error #1003 and it says the archives arnt correct or somthing

if you are trying to upgrade from 1.0 up and you get the 1003 error it means your PC is preventing the updated from extracting the downloaded zips.

You can either find the blocking program and make an exception for the LBML folder or just unzip the update folders incrementally by hand.
and overwrite the files in the main installation folder.
