How to revert Razer Synapse?

Hi, My question is simple and i'm going to make it fast because i'm really pissed of this software. How to revert the recent Razer Synapse update back to the old version? Since the update the software went from 100% stable to 0%. Everytime I shut-down my pc I get a message error. Everytime I launch my pc, the software asks for admin permissions for changes. After an hour or less the software crashes for no reasons. When i'm just changing a simple equalizer for my headset it frozes. When you try to send a feedback from the software, after you've hit done it loads, it loads, it loads forever... This is not the first time an update fuc* up something so please stop updating or at least give us the feature to block updates. Everything was working fine it was 100% stable and I have no errors, annoying messages, bugs, froze or any-anything but now it's awful. I wanna ask, did Razer got hacked? People who are going to say just reinstall it well sorry but i'm not going to reinstall it after every single updates + i'm currently having network issues so re-re-redownloading a software just because of an update won't do it for me. So if someone has a solution or a download link from the previous version of the software I'll be glad to have it thanks!
