Hi

I'm a beginner to IDA Pro and Paimei and was practicing generating PIDA file for calc.exe using "pida_dump.py". When I run this script from IDA Pro I get the following error. Please help me in fixing this error.

I'm using IDA PRo 5.5 and python 2.5 and recompiled "pydasm.pyd" as mentioned at this link
(http://www.openrce.org/forums/posts/633) but i have used libdasm-1.5.tar.gz from
(http://www.klake.org/~jt/misc/libdasm-1.5.tar.gz) instead of libdasm-1.4.tar.gz

I have downloaded Paimei 1.1-REV122 from http://www.openrce.org/downloads/download_file/208

Thanks
