11 Apps Fail to install with "Downloaded copy of XXXXX is not valid and can not..." see pix

Hi,

Today I have 11 apps that won't update PAI 12.0.5 (windows 8.1 x64) . I have a few that did Libra Office was one I noticed.

Is this a temporary problem? When can a fix be in pace?

The list of apps are (I couldn't find a log file and I can't attach screenshots so I am typing them in manually):

- CrystalDiskMark 4.1.0
- Filezilla 3.12.0.2
- Free Download Manager 3.9.5.1559
- Google Chrome 43.0.2357.134
- GPG Plugin 2.028 14

- PortableApps.com Installer 3.0.19
- Process Hacker 2.36
- qBittorrent 3.2.1
- uTorrent 3.4.3.40633
- WinDjView 2.1

I do use windows sync tool to backup to another usb stick but this is the main one not the backup...

Help?

Thx
