Zoints Thread Tags Problem

[Mean]

I accidently disable the Zoints Thread Tags.
When i enable this again, the thread Url's have been changed like this:

/motorlu-araclar/5299-dunyanin-en-gelismis-arabasi.html

/motorlu-araclar/5299-duenyanyn-en-gelithmith-arabasy.html

These words were

ş > s
ı > i
ö > o

Should be like this. When i use ş,ü,ö.... in thread titlesi it still doing that.
How can i fix this ??
