The reasons for DLLs being missing can be numerous,
though pirating software badly does account for this remarkably well...
Lerner04, if you own the original disc, i suggest yo ure-install the program, this will replace any missing files. If you don't own the software, then you don't really have any business using it...
There is no site where you can just download DLLs since these are coompiled files and are covered by the same copyright law as all the other parts of the program.
