Hello, when I try to update the software, I get the following error message:

Status check complete.
78 files are up to date.
1 files have an invalid signature.

The file in question is the DelZip190.dll file (version: 1.9.0.107 17.08.2012).

What can I do to solve the update issues? All files are old and not current. Even where it says that a newer file is online, the software doesn't update itself automatically. How can I get the latest files? What do I have to do to get them installed?

Thank you for your help,
best regards,
Kelley
