[Dev-C++] can't compile anymore after upgrade to 4.9.9.0

[A. K. <kli...@ad...>]

I upgraded from 4.9.8.10 to 4.9.9.0 and now I can't compile anything: it 
seems that g++.exe is called from the wrong directory:	

Compiler: Default compiler
Building Makefile: "D:\lang\projects\PyScript\Makefile.win"
Executing  make...
make.exe -f "D:\lang\projects\PyScript\Makefile.win" all
g++.exe -c PyScript.cpp -o PyScript.o 
-I"d:/lang/Dev-Cpp/include/c++/3.3.1" 
-I"d:/lang/Dev-Cpp/include/c++/3.3.1/mingw32" 
-I"d:/lang/Dev-Cpp/include/c++/3.3.1/backward" 
-I"d:/lang/Dev-Cpp/lib/gcc-lib/mingw32/3.3.1/include" 
-I"d:/lang/Dev-Cpp/include"  -DBUILDING_DLL=1  -ansi -mwindows 
-fmessage-length=0

g++.exe: PyScript.cpp: No such file or directory
g++.exe: no input files

make.exe: *** [PyScript.o] Error 1

Execution terminated

I then uninstalled Dev-C++ completely and deleted its config files in 
Documents and Settings too, then reinstalled: same problem.
The "no input files" happens with each and any project I try but the 
.cpp files do exist. Any suggestions on how to tell dev-c++ the proper 
project directory (d:\lang\projects\PyScript in this case) and making it 
the current working directory? Or any suggestions what other problem 
could give me that error?
