Too many activations error, needbto have my activations reset.

I only use two devices, but apparently an app counts as a device.

Anyway, I need to activate a new e-reading app, and I am getting this error. Tried deauthorizing two appa but that fid nothing. Contacted the live support via chat, but Ramesh G. said that I should post my issue here to have my activations reset.

Thanks!
