Opencart Exported Needed To Fix Feed Import

Im after a opencart expert to fix a issue with our feed import It runs fine on version 1.5.3 but wont work on new version 1.5.4.1 Feed import uploads the csv file to system/cache folder and uploads the items to the store Nothing is to be changed only fix issue so it works on new version im presuming something has changed on new version so no longer works. Only Opencart experts bid as its a small job for the person who knows about opencart will not look at bids over $40
