Traktor Wont Let Me Import Samples

I just downloaded a new sample pack and i can usually just open them up and use them in traktor no problem but for some reason with these Traktor wont analyze them and when i try and load one into a remix deck it crashes traktor! They are in wav. format and have alot of meta data already written to them like bpm and length, the work fine in ableton and play also play in itunes. The release notes mentioned something about "acidized" data, could this be the cause of the crashing and being unable to use them? Any help would be awesome i really like this sample pack. Thanks in advance
