Some addons don't work anymore

Hello.
I picked up a new PC, with windows 10 and an SSD. Ever since, *some* addons don't work anymore. They all appear in the character selection but not ingame. This has never happened to me before.

Out of these Addons, Bagnon, Auctionator and OmniCC work. Recount and AV don't appear ingame.
I simply get a "Type /help for a listing of commands" hint when trying /recount show for example.

They also don't appear in options.

I'm clueless, this has never happened and I play since Molten. I've tried about everything I can think of
- Client is from Warmane and it worked fine before
- the addons are unzipped
- the addons are in the Interface/Addons folder with correct hierachy
- tried to run as Admin, or disable read-only mode
- Outdated Addons are being loaded (none are outdated)
- Tried disabling and enabling WoD models
- moved to desktop / downloads / program files
- deleted cache and wtf

I've seen similar topics, but they always are left for dead, or a fix not being discussed. Thankful for any help

i have the exact same issue, the only thing that is different ony my new pc is windows 10aswell...
any GM can address this issue? its being ignored for quiet a while.

i got the same issue! if u guys find out how to fix it please let me know

It's becoming gamebreaking now, this problem also appears with Omen Threatmeter, while playing a tank

I found a fix, if a weird one. Installing "AtlasLoot" addon, suddenly all other addons worked, Omen, Recount, AV. Removing AtlasLoot disabled them all again. Hope this helps you other guys
