In PostConform 2.0 there is no automated process that batch links all files to all source events. What this means is that you will have to manually point PostConform to the correct source files. Hopefully the name of the source file will correspond to the event source but sometimes you may not be so lucky. In these cases you will have to cross reference the Start Time, End Time and Duration of both the event source and source file to make sure that you've got the right one.
