Encore CS3 crashing at every turn

I have had CS3 installed for a few short days and so far every little thing I
try to do is not working out for me, wow is that frustrating...

I am assuming that there is some kind of installation problem now or something
wrong with my computer so I thought I'd try this forum.

I have had Encore crash on me (1) when editing a menu in photoshop, (2) when
exporting a project to flash and (3) my second try at importing a blu ray m2v is
crashing it before it hits 1%.

My system is an AMD Dual Opteron 250 with 2 GB of RAM and XP Pro.

Any help would be appreciated.
