Hi MrsForty,
If you want to do a clean install since the last two setups worked for you.
First un-install your PGP product and reboot your computer. If hard drive is encrypted then the drive would have to be un-encrypted before un-installing the product.
Go to your Windows run and Type %appdata%. A Roaming folder should appear and click on the folder. A window opens with a list of folders and look for PGP Corporation folder. Delete the folder. This folder holds the policy and prefs file of what your settings were when PGP was un-installed.
Re-install your PGP software and the install should be like a brand new install.
If this doesn't resolve the problem then this maybe an issue with the LSP protocol that PGP installs on the computer which has caused some e-mail issues. This can be resolved by disabling the component at install which you'll have to call Techincal support so they can do a webex to help you disable this.
Tech Support is all live call to help assist you with your PGP
Thanks
Anthony
