Guess, I'll have to bite the bullet
I've never had to do this with Hoster before and since I thought I waited until all the bugs were fixed, I assumed everything would work the first time.
Since this is an upgrade, do I uninstall the usual way (through the Control Panel)? Since that will remove all instances of Hoster, will 4.03 still install without a previouis version still on my machine?
Also, is it possible that 4.03 uses many more resourses than 3.321? My older laptop did have a lot of other programs on it that ran just fine with 3.321, but maybe they conflicting now, even though they didn't before?
