I tried deleting WTF folder, reinstalled multiple times. Here is the error report. (Its rather long) I am in the US servers.
I bolded the portion that looked significant.

Got the problem resolve, thank you Tiny!

Hello!
I don't mean to bump an old thread but I'm getting the same bold message for my oQueue. I've downloaded it and extracted it twice and made sure that I do not accept any auto-invites (I use Tukui). Can anyone please help me with this? :(

Edit: Just deleted my WTF folder... all is well and I feel like an idiot haha thank you!

same error telling me to update, but i keep geting the old version when i download it again. halp!

Ide suggest probably downloading the Icebox self installer client from the Apps dropdown in the navbar. Use it to install oQueue.

This will help ensure you are getting the newest version.
