Mio with IGO doesn't startup anymore

Hello,

I do have a Mio spirit 575 and a long time ago ( 5 years) I installed a program on it so I could use IGO and Tomtom on it.
I only used IGO and today I updated the IGO maps , poi, etc but now IGO ins't starting up anymore.

When I start up the Mio I see: SEEKER.R16.00.0773.STF128M
Then I get the screen in which I can choose between IGO and TomTom
When I startup IGO I see the startup screen from IGO but then I get again the screen with SEEKER.R16.00.0773.STF128M and it goes back to the startup screen in which I can choose betweeen IGO and TomTOm

What is going wrong ?
