[Cooker] Mdk 7.2 beta: installation problem

[Veronica Miron]

dear all,   during the installation of mdk 7.2 beta on my laptop (PII) right after the keyboard selection i got a message: CAN'T CALL METHOD ASK_WARN ON AN UNDEFINED VALUE. and the installation doesn't go further and stops at partitioning.   i tried the installation from the same cdrom on another computer (Athlon, not a laptop) and it worked perfectly. then i also tried other 3 laptops (PIII) and it always gives the same error message.   is there anyone familiar with this kind of problem?   thanx and greetings   veronica
