> Do you know if the STK500 can be put back, so that it is compatible
again?

Funny you should ask, as I had to program a few Tiny15's this morning.
Yes, you can re-load the old firmware.  The file you need is called
C:\Program Files\Atmel\AVR Tools\STK500\stk500.ebn if you did a normal
install of AVR Studio.  

I loaded stk500.ebn from Studio 3.55, programmed Tiny15s, loaded
stk500.ebn from 4.08 and went back to playing with the Tiny13s.

The load routine is in Studio 4.08 under Tools>AVR Prog.
