I'm not sure what the problem could be other than what I've already posted here and from the other threads on this site detailing the use and functions of the AR.
What I have found though is that there are a number of things can prevent the card from either loading properly and they're all posted on this site.
1.Bad AR cards are most common,so replace it.
2.Card does not have enough space to load if items already exsist on card,clear card and reload.
3.Delete "Datelfile" a must in order to download file to XBOX hard drive.
4.System must be able to download and configure Zip files.
These are a few items to keep in mind when using the AR,sometimes after loading a zip file to my XBOX I'd recceive a "Damange file or ??? in that case I would delete the file from the XBOX hard drive also I would clear and erase the card and confirm that by seeing that there should be 502 blocks available.
Also I would check the cards space and AR status by seeing it on the AR screen which should show only the memory card on the screen and no files loaded in other words the card is clear and all 502 blocks are free.
Other then these items I've mentioned here and along with other info at this site theres not much eles I could say on the matter as I've already posted most of what I've found that works for me and along with the AR thread these should help to eliminate or at the most help narrow down just what the problem or problems maybe with you loading issues.
There is a thread that refers to these problems in further detail and perhaps other gamers could help in a disscusion,as for myself this is about as much as I can say or do on the matter so if you've tried everything here and have found no sucess then I'd seek further information from those sources available in other threads the deal specifically with the AR functions and uses.
