This is because your order has expired and deleted. Users are given five days to download their orders and0 after five days orders are automatically deleted to make space for other orders.

We investigated your orders and these are very big. The post processing that you applied is generating a large number of files for each order. You are converting all MOD09GA layers to geoTiff, so even though there are only 350 or so input files in an order, there are many more output files, one for each layer:
OrderId | FileCount
-----------+-------
501817706 | 16060
501817747 | 17424
501817808 | 15708
Any listing with more than a few hundred files starts taking a long time and is more likely to time out. You could subset by SDS to get only the layers of interest, which will cut down the number of outputs.
