The first file (Pumpeopgaver#.mcdx) appears to be corrupt beyond repair. The file contents are just a bunch of NUL characters. Hopefully you have a backup somewhere.

The second file appears to be repairable. However, since I only have Prime 3.1, I just get an incompatibility error when I try to open it. Can you tell us what error you get when trying to open it in Prime 4.0?

EDIT: for the first file, there's also a possibility that it just didn't upload properly. Probably unlikely, but worth checking. On your end, right-click the file, choose "open with" and open it with Notepad or similar. If it looks like a bunch of spaces or NUL characters, then it can't be repaired.

EDIT2: I decided to go ahead and install Prime 4.0 Express. After doing so, I can open the second file without problem. As noted above, please indicate what error you get when trying to open the document.

Hey thanks

I just did try downloading both files that I did upload at this site. Now I can open the second file. But not the first file. At the start I got the same message from Mathcad at both files. About the file type is not at mathcad prime file.

Is really strange...

I won't bother to look at the file, because I trust MJG. If the file is all NUL characters, it's permanently trashed. This problem is years old, but PTC is either unwilling or incapable of fixing it. Sorry.
