You need to know where you saved them before reinstalling Hoster. They may have been in C:\Program Files\Micro Technology Unlimited. When you install 4.06 it seems to store them in C:\MTU\Hoster
So have a look in the previous directory and see if they are there. Else do a search for ".hst" without the quotes. You don't say which version of windows you are using but if it's Vista open the drive from my computer that you had them on before and type .hst in the search panel top right and it should find them. Then take a note of this address and from Hoster /File/open point it to the old address.
