Web Management console logon error

Hi,

We are currently using Mirage Version 5.6 and are hoping to upgrade to Version 5.8 to take advantage of the Windows 10 support.

Currently, we are not using the  Web Management Console and as it is an important tool with the latest releases we decided to try and install it. We downloaded the relevant msi file (mirage.WebManagement.x64.130302 - the 5.8 version) and this installed ok so we get the expected login screen.

However, when we try and login we get the following error:

Any ideas to solve this would be gratefully received.

Thanks

Robert
