WantGCIn2005,
there should be a lot more than 33 cases for 485 on any particular day. Typically the number is between 130 and 200. Did you run the scan just once for the whole range (50000 - 54000). If so, it may have errored out after the first 200 cases were scanned and you probably didn't notice them.
You need to scan in sets of 200 cases at a time. (ex: 50001 to 50200, 50201 - 50400 and so on). If you have a dynamic ip broadband, you can simply reconnect and scan each set of 200 cases. Otherwise you'll have to wait till the next day to scan the next set of 200 cases(can take upto 20 days to run the initial scan for a single day's worth of cases).
It becomes a lot easier once you identified all the cases (typically less than 200) as you scan these cases every single day without being subject to the daily limit.
Thanks,
