Fail when activating

I got the white screen of death 2 days ago after updating Jetpack Plugin. I had to delete plugin through FTP access and got my site running again.

After installing your new update, I could nok connect to wordpress.

I deleted plugin once again, but now I can install the plugin, but when I activate, I get a white screen with an error. I can access my site, but I get the error when I try to go to the admin controlpanel. The only way to get in, is to delete the plugin through FTP.

I want to use the Jetpack plugin again just like the last 2-3 years – what is happening? And what can I do?
