You should’ve searched this Forum on how to install themes for SMP.
Because you’ve got it completely wrong.
(This was posted in the wrong section, but it is a Guide to Installing Themes on the SMP)

P.S. Once you’ve copied the “Linksheets” into the CoCo (Linksheet) folder you then must ZIP it at Root Level using
No Compression (aka. Store in Winrar) and the “Submit” CoCo (Linksheet).zip to your SMP.
Also as stated previously, you have only got a 24MB of free space for “Linksheets” (The WDTV Live Hub has it’s 1TB Hdd to store Linksheets)
