Hope that problem already have solved itself, bur for future reference I'll give you an answer:
If you have run your simulation and the result file is loaded (you can check that in the result tab and otherwise load it into mike urban via the generated file from the simulation).
Then choose time series, choose what object you wish to display, and then click the desired link, manhole or catchment. You can save the result from there as a .dfs0 file. or export it to desired format.
