Nonlinear fitting with latest MMA 10.4.1 vs MMA 7?

Hi expersts, in the paper *Golicnik, M. (2013). The integrated Michaelis-Menten rate equation: deja vu or vu jade. Journal of Enzyme Inhibition and Medicinal Chemistry, 28(4), 879-883. doi:10.3109/14756366.2012.688039 there is used Mathematica version 7 with an nonlinear optimization, which might work fine. But in the latest MMA 10.4.1 I get an optimization error: see pic attached enter image description here .

Can anyone here help me, in making the NB working for the latest MMA? I just realized that it works fine with only 4 datasets.

But can anyone here tell me how I can plot the solution sophistically? I have attached the new NB here.

Thanks Mariusz, for the Verification. The originate problem was, that I had some wrong data points, so the ODE could not be solved. Now the data is updated correctly and it works fine again. Best

Ok.I'm no expert.You can tell me, base already met.

I do not have a MMA 10.4.1 only 10.2.0.In my version it works.

Please see uploaded file.
