Titanium Backup wont get root

Hi,

ehm soz for my bad english :)

Im running Android Revolution HD-One M9 12.0 ! All works fine

SuperSU was preinstalled!

I got rrot access there for sense tool box, root explorer etc.

Today i installed Titanum backup and now its getting interesting:

Installed - opend - SuperSu askes for permissions - press allow

Then Titanum said "No root......" At the same time i see the small HTC Windows who says root is allowed ???

So o tried do delete data in settings - apps - titanium and also for SuperSu

Tried it several times but it wont work ???

Anyone got similar Prob? It couldnt be much because SuperSu is working is asking and WTF :D

Thx all
