Spellcasting problem

[Arutan]

Hi,

i use PRC 3.5, with NWN 1.68 (german), Windows 7. I play in compatible-mode.
The problem is, that i cant cast spells with my casters.
For example: If i try to cast "Mage Armor", after the casting animation nothing happends and i get following error message:

Script NW_S0_MageArm, OID: ffffffff, Tag: FEHLER: Stapelunterlauf
                                        (in english: day: ERROR: no idea  , something with "stack...")

(Oh, and I´m sorry for my bad english.  )

Edit: I have tryed several re-installs and different versions, nothing helps)

Which module do you use? Any custom content installed (custom AI systems?)? Do you have anything in your override folder? Did you tried to cast form bioware or new spellbook system?

The official NWN core campaign. No to the custom content and no to the override folder. I tried to cast from the core bioware system.

But it seems that the patch 1.69 had solved the problem. At least in the start area, the spellcasting is working now.
