what is going wrong? I think that the export should work with spaces in 
the name alright. On the other hand you will need an extra pair of "" 
for the Run statement, which must be escaped e.g.:

Run["start excel \"C:\\Users\\albert.retey\\Desktop\\tst 2.xls\""]

Note that you could just as well save to xls format instead of csv, once 
you have restructured your list to represent the array you want to export.

Here is another version for that restructuring, which should work for a 
list with arbitrary many arrays of arbitrary dimensions. It inserts an 
empty row between all arrays and then "flattens" by replacing List with 
seq and then seq with Sequence:

data = Block[{seq},
   Riffle[seq @@@ (Transpose /@ list), {}] /. seq -> Sequence]

hth,

albert
