Ok, I did a bit of research but coulnt find anything.
I just reinstalled Windows and made partitions C,D and E.
"C" should only be for Windows and I left it with 15 GB.
I installed PostgresSQL8.3 on "D" (and replaced my database) and HM also on "D".
Now HM cant find Postgres because it is ONLY looking on "C" for it.
Is there a chance to tell him it is on "D"?
I could reinstall Postgres on "C" but there will be not enough space sooner or later.
