Now why oh why didn't I listen to my head and NOT take your advice? I followed the purge instructions exactly, and even made manual backups of the stardock user folder and registry key, reinstalled and it's a MESS. It has retained my fences (& no longer brings up the option screen on startup), but...I'm now on 2.13 when I was on 3 before, the settings-window's font is miniscule at 4k, and I can barely distinguish the individual snapshot images:

and the icons on my 2nd (1920*1080) monitor are spaced massively apart:

(the icons on the left are not in a fence, the centre-screen icons are all in one fence):

note the huge gap between non-fenced icons on the left (next to my vertical taskbar). I should have known better than to EVER consider a "purge" as a solution to a minor issue

Because the secondary download (the one that starts after you run the installer stub you download) kept failing for 3.x. After "upgrading" to 3.0.9.11 the spacing and small font issues are resolved, but I now only have a 30-day trial of Fences 3, and when my keys are emailed to me I only get a key for 2.x? I BOUGHT 3.x, that's why I was running 3.0.9.11 when this mess started?

Ahhh thank you, perhaps that could be made a little clearer in a users' details somewhere?
