Hmm, strange. I guess maybe you have Data, Images, and Video turned off? Which would happen if you were in Audio Only Mode. (View menu > Audio Only). Or you can turn those things on and off individually. Tools > Options > General > Features > (select features here including Data) .
I'm not sure why it would be importing things that aren't in your feature set though. Do these log files in in ".log" ? Or some other extension?
