Which version are you having trouble with? PC? Mac? The Estrada Android port? I need more information.

Interesting. I zipped it with the standard Windows Right Click > Send to Compressed (Zipped) folder thingy so there shouldn't be any problems unzipping it. Are you getting an antivirus trigger when you try to unzip? Could be you need to whitelist it in order to be able to unzip it without stuff going into quarantine.
