Files extraction problem

[Vanz 6]

Hi everybody, i don't know if this is the right section for this topic, anyway i have downloaded the BSC Common Dipendencies pack v9b and  i have tried to extract the files with 7z program manually because for the moment i want only 2 files in this big archive, but during the extraction 7z at a certain point stop to extract and an error with the same name of the file appear, but i can only close the 7z window and so i can't extract this dependencies, i have tried this 3 times and is always the same, anybody know what can i do? Actually the files that i need are only 2, "jenx medieval houses prop pack" and "bat props jenx vol 2"  and i find them only in this huge archive, i need them for the building models of  "jenx  fachwerk houses" and "paeng old town center", if there is an alternative way to have only this 2 files without downloading all the mega archive will be great, and if there is out there other medieval buildings sets let me know, thanks to everybody and sorry for my english

Update, problem solved by myself, i have downloaded and extract the file with another pc and internet connection and it worked, maybe my java version is not the latest
