Update the new 0.80,download the new demo.
found the lovelanche.love and metaballs.love run error.
but after unpack the file,run in the SciTe,it is run OK
the error in the lovelanche.love is
main.lua:29:Incorrect number of parameters
Traceback
[C]:in function 'newWorld'
main.lua:29:in function 'load'
[C]:in function 'xpcall'

the error in the Metaballs:
main.lua:13:attempt to call filed 'isSupport' (a nil value)

I had changed the "open mode" to the new love.

It seems like you're running the demos with LÖVE 0.7.2 rather than 0.8.0.

[poorenglish]

Yes ,I know.
So,I delete the 0.72 version love.
And change the "open mode" to the 0.80 version.
the result?
and I change the open love file to Adobe Reader 9.5
It seems like can't change the open mode to the love 0.80,
I use the Zipped 32-bit,in Win7.
I will try the Installer 32-bit version.
After use the Installer 32-bit version,it is OK,it is my wrong.
