AX100 Navisphere Express not accessable

Well, to get right to the point:

Without knowing that i do sth stupid, I pulled the the top 3 (and later the fourth) disk which contained the FLARE OS. Now i cant access the navisphere express UI anymore. Even a ping wont respond.

Is there any way for me to get access again?

I dont have any FLARE OS or navisphere software available, because its just an old product from our university for a testlab.

Is there any way to get access to the software?

Otherwise work of about 4 monts will be fruitless in that case..

best regards
