[Icecrown] Macro issues! D:

Hello,

I stopped playing for like a month or two because of work, and when i came back some of my macros weren't working. Can this issue be related to some new fixes on the Icecrown server? Besides that, the only thing that changed was my windows, went from 8.1 to 10.
I'll post the macro here, just in case i'm wrong and somehow messed up the macro without noticing.
The part that isn't working is the "/use [mod:ctrl]Wound Poison VII...".

#showtooltip
/cast [spec:1,mod:alt]shadow dance;[spec:1,nomod]shadowstep
/cast [spec:2,mod:alt]tricks of the trade;[spec:2,nomod]killing spree;[mod:shift]kidney shot
/use [mod:ctrl]Wound Poison VII
/use 16
/click StaticPopup1Button1

Already tested the poison part alone, and it does work. What could be the issue of having that in the same macro if it used to work before? I don't get it.

Thanks for your time!

Figured that the only parts of my macros that aren't working, are the ones with the "[mod:shift]" part. Is it server related?
Btw, using bartender4 as a keybinds addon.

just change it with modifier, but im not entirely sure if it is that mod doesnt work in wotlk, or due to a warmane bug.. anyway, use the full word, and it shall be ok :)
