RipBot audio can't be encoded??

[crankharder]

All of a sudden, after several successful rips, RipBot stopped creating an output file (after 4 hours of churning). Digging into the logs I that RipBot can't get the audiostream out of C:\temp\RipBot264temp\job1\job1.avs That file is present, but is only 1KB. Should it be more? How could this have happened?

Relevant section of logs:

C:\>"C:\Users\jsharpe\Desktop\RipBot\tools\bepipe\bepipe.exe" --script "import(^C:\temp\RipBot264temp\job1\job1.avs^)"   | "C:\Users\jsharpe\Desktop\RipBot\Tools\enc_aacPlus\enc_aacPlus.exe" - "C:\temp\RipBot264temp\audio.aac" --lc --br 262144 --mpeg4aac
