Universal Media Server | Forum

You can download and install any older version that you want. Just make sure to disable the automatic update. You might need to delete the database though, it depends on whether it has changed between the two versions.

Regarding the database, I don't know if it applies, but if it does you can find out how to delete it by searching this forum.

If you are using windows, the database is located in "C:\ProgramData\UMS". renaming or deleting the database directory will make UMS create a new one.

I think this latest version has doubled the allowed amount of memory used by UMS if there is plenty available to improve efficiency. I think it was originally 1024mb and now it defaults to 2048mb (can't remember exact values) but this can be changed on installation.

If this change is the cause, it may be helpful to the devs if you could post some logs.
