Home Studio 7 and music creator 5

You will pardon me if this question has already been answered before, but I have't seen it.
 
I had owned Cakewalk Home Studio 7 and had a few wrk projects that I would like to finish up using music creator 5. The problem is when I open the file I get several error messages about missing files. I don't know the names of these files off hand, but they seem to be connected to Home Studio 7 (which is currently not installed on my computer).
Do I need to install it before I can use them in the MC5?
Any help or suggestions would be greatly appreciated.

okay here is what the program is looking for:
 
CV1mn14i2.WA~
RC1mn1efl.WA~
 
If I skip the files, I get:
 
Some external audio files cannot be found. Missing audio file data been replaced with silence.
 
And play back has no sound. Iam not familiar with the two files its looking for.

 
It sounds to me that he has loaded a saved "project" file and not a "bundled" file, which means the audio wav files were not included with the save.
 
But Beagle's suggestion is a good one. Maybe the audio wav files are there somewhere but the MC program is looking for them in it's default folder and the audio wav files were saved to a different folder.
 
Are all the audio files missing or just a couple?

According to MC 2003 help file, the only Cakewalk program I have that references .wrk files, a .wrk file is all your MIDI data and project settings. The audio is saved in a different place on the hard drive.
So, if the files are in fact .wrk, there is no audio there. If you don't have access to the hard drive that you originally recorded this on, that audio is gone.
 

 
See....I told you so, I told you so, I told you so.

Sorry 'bout that...
Since Cakewalk has changed their file extensions and you don't want this to happen again, save your work to CD/DVD as bundle files. These contain everything, including the audio, and you can load them up in any computer with a modern Cakewalk program installed. In the old days, these were .bun files; now they're .cwb files. They are very large, too.

Nah, before SONAR Home Studio there was just plain Home Studio.

Very often, if the files were recorded and saved in an older version of Cake, they can be opened in most current versions. I had some old Cakewalk pro 8 files that were saved as bundles. (Very important to save your work as BUNDLE files as Greg said above)  I popped the CD into my lappy and opened them successfully in MC4.  I think it only work from old version to new...if you try to open a new version MC4/5 file on an older version, you might not be able to do it.

However, if you did not save the audio files and do not have the hard drive where they were saved to anymore..... this is a good opportunity to record those tracks again. As you have said, a few years have passed, so hopefully your playing and chops have improved and they will sound even better this time around. Just save what you don't want to loose this time to a CD as a BUNDLE file.
