InvDel doesn't work

I'm living in Germany, but i will try to explain my problem in english.

The plugin InvDel 0.2 from the Devil project seems to be not working.

From the log:
[23:36:09]Remove From Inventory: 1 deco_basketballcourt
[23:36:09]Delete Gifts: deco_basketballcourt Have:1 Keep:0
[23:36:08]Remove From Inventory: 1 deco_rosewall_corner
[23:36:08]Delete Gifts: deco_rosewall_corner Have:1 Keep:0
[23:36:07]Remove From Inventory: 1 deco_giraffe_icesculpture
[23:36:07]Delete Gifts: deco_giraffe_icesculpture Have:1 Keep:0

Then i logged in into CV and checked my inventory. All these items were still there.
So nothing was deleted.
XP SP3, admin rights, firewall is off, MS Visual C++ 2008 with all updates is installed (also 2005 and 2010), tried with AV temporary disabled

Any idea?
