For some reason right now when I try to install a thing from the DLS on Content Manager, it just says "Searching Asset" and does nothing else, but for some reason when I install from the DLS website it works
We're currently migrating DLS databases to a new server which will address the issue of slow dependency searches. Sorry for the inconvenience while we carry out this necessary maintenance.
In my experience this has nothing to do with your login, and if you look at your Trainz login status you'll see that you are logged in. This seems to be a server access issue.
I had the login error, just opened the settings for internet and closed it and all now fine. As they have migrated the DLS to new servers probably just needed a nudge in the right direction.
