Users have gotten their various 32gb cards to work, but really a case of hit and miss and some headaches along the way. The link provided by @marioguttman suggested he used a Kingston 4gb card where you are trying to use a Kingston 32gb card. Roku sells 2gb on their site so really does seem like using a lower gb card may be your answer. (I think some of the Roku devices may just not like the larger cards...also unnecessary as it doesn't give you any more additional storage...Roku will only use "up to" the 2gb of any card you use.)
