Running window version of AA in window 7.
Since I was playing this game in laptop, I couln't use the keypad numbers, so assigned them to non-keypad numbers. Also assigned the spell casting button to 'F' and abort casting button to 'B'. Even though I had all the corresponding runes and indeed ordered the runes corresponding to the appropriate magic I wanted to use, any magic couldn't be casted. Only leaving the message, 'YOU FEEL SOMTHING IS JUST NOT RIGHT'.
Now reinstalled the game and backed up the character files. This time I didn't do anything about key assignment. Now magic works.
This time assigned the spell casting buttons to something like 'i, o, p, k, l, ;, ,, ., /'. It didn't work either

Maybe I've done something wrong then forgive me and please erase this topic.
My assumption is that the default assignment of the spell casting buttons(i.e. rune selecting buttons) shouldn't be changed, which means I cannot play any further. Oh my ...
