I own neither.
The easy answer is in the D90 manual, something like "use only Nikon ...".
The other one is: contact the dealer where you bought the remote, if he/she stated compatibility with the D90, they are responsible to make it work.
One other item in the D90 manual: selecting the right remote mode, page 68 or thereabout.
