ok here is the trick. Took soem time to figure it out

1) install 2_10
2) use the application without importing handyshopper files(config
palm backup directory etc)
3) unzip all files from 2_12 into where the 2_10 is installed
(overwrite the 2_10 files)
4) copy the IconList.TPS from Files(in this group) and overwrite the
one in the ratshopper install directory on your computer
5) unzip the files from 2_15 into where the 2_10 is installed
(overwrite the 2_10 files)
6 ) open RatShooper, go to help->enable me. Don't do anything just
click ok->ok.

Now, the problem is I cannot open the hs2 files (*.pdb). I get "file
access error"
