[ic] Interchnage 4.8 eror help plz

[Gaby]

Hi All.

I have some problem when running interchange with apache module
I got next errors in debug.log 

Died in server spawn: options not a database, cannot use as products file

Died in server spawn: Can't call method "new" on an undefined value at /usr/lib/interchange/Vend/Data.pm line 674.


And in browser "Internal Server Error" 
So I can't run Interchnage .
Also I can admit that it  can appear suddenly ,but when I reload page  5 or 6 
times it sometimes keep running with no problem .


Thanks for any sugestion
Gabi
