E-5 and PSE 7. Can't open raw files. Help!

I rented an E-5 for a trip to Colorado last week. I shot in RAW one day and the rest of the time in RAW and jpeg. I can't open by raw files in PSE 7. I usually use an E-510 and have had no trouble with raw. I saw another post on this subject only with PSE 9 and I went to the Adobe web site. Am I missing the link to the plug-in I need? Hope someone can help. Thanks.
