Problem after upgrading from Mathcad 2001 to Mathcad 14 M035

[HorsensHtx]

After I have updated to Mathcad 14 M035, Mathcad can not calculate my documents correctly, but it works fine in version 2001.

What could be wrong? - I've attached an example where I can not get Mathcad M035 to figure it out.

In version 14 the symbolic engine was changed from Maple to MuPad. it seems it can't cancel the units. Strictly speaking, this is not a bug but a missing feature. It's a really bad missing feature though!
