Downloading problem

[Panjack]

I'm trying to re-download a game file from "my page." When I do, nothing downloads but I get:

SLITHERINE DOWNLOAD FILE SERVICE
Error ( Code: / )
file to download: GaryGrigsbysWarBetweenTheStates\GaryGrigsbysWarBetweentheStates-SetupRelease-v1030nDR.zip

This happens with all old games I try to download. And, the server use shows 0 use of all individual servers no matter what the location (US, Europe).

Further, when I click on the "contact support" link I get:

Oops! An Error Occurred
The server returned a "500 Internal Server Error".

Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

This happens in Firefox and in Chrome (Windows 10) along when I try to download to my phone.
