Nokia 7250i

Ok I know its an old phone but I have got some pics on there that I really need to get off. i have a dku5 connectivity lead and have downloaded nokia pc suite and the driver but when I connect the lead to my pc it wont recognise it. has anyone else had similar probs with this and can anyone offer any advice? Any help would be great as I have pics of my newborn daughter on the phone which I am eager to recover. Thanks.
