Well I dont know the app but if it is use by way of installing it then maybe uninstalling it and then re-installing it. If it is a web application then you may need to clean up your temporary internet files and temp folders. Use the disk clean up by right clicking on local (go to my computer and right click on hard drive), then left click on properties, you will see disk clean up or something like that:) if none of that works then go to facebook and post your problem their and someone will now how to assist.
