1) delete the hack (which you can only do a Continue Install or Delete Hack for);
2) make sure that that hack's .htl file is in your /htlfiles/ directory;
3) Go to Install Hacks, then select that hack (via the radio button), then start install and choose IMPORT TO DATABASE ONLY;
4) You'll end up directly on the Manage Hacks page. Go to Edit Hack Details for your hack, which should be in there again now, editable and all;
5) disable all steps that you have already executed successfully;
6) Save, then go to the hack's (on manage hacks page) drop down menu and choose Run Install Sequence, then choose Real Install and continue where you left off.
