vc++ express stoped compiling anything :(

hey there.
i have a serious and weird problem.
since yesterday i can not compile anything in vc++.
the compiler (cl.exe) just runs through without doing any output.

i just get a linker error (no other errors), for wich the reason is obvious, since the compiler does not output anything ( hence no *.obj files produced for the linker)
there are no compiler errors either. nothing! my ide tells me it compiled succesfully, but in fact nothing was done.
build log seems ok too! even if i feed the compiler with faulty arguments or obviusly faulty source code, it just does nothing.(doing so from the command line)

it seems to me that cl.exe is broken (or some dependencys, as i already reinstalled cl.exe along with a new visual studio installation.

i already reinstalled visual studio.
nothing changes.

do you have any idea?
i'm in serious trouble, as i can not do anything right now.
i posted this in some MS forums too. no answer yet.
thought of switching ide, but can't get them (Eclipse/netbeans/qtcreator) to run either (for other reasons thought, too much JUCE/VC++ dependent stuff).

p.s. maybe you could do me a favour and tell me wether your cl.exe produces any output? shouldn't it print its raguments when simply started from the console? or an error message when fed with bad arguments?

thanks.
