Quartus II 12.0 - Internal Error: FIOMGR

[Altera_Forum]

I'm trying to compile a small RAM module, I received the following internal error pop-up:  

 internal error: sub-system: fiomgr, file: /quartus/fitter/fiomgr/fiomgr_io_power_region.cpp, line: 3221 part_info_loaded stack trace:  0x15313: fiomgr_io_power_region::reduce_supported_voltage_with_voltage_db + 0x123 (fitter_fiomgr)  0x7255e: fiomgr_io_manager_impl::set_up_device + 0x153e (fitter_fiomgr)  0x6ef4d: fiomgr_io_manager_impl::init + 0x21d (fitter_fiomgr)  0x2fbe1: fiomgr_io_manager::create_manager + 0x721 (fitter_fiomgr)  0xd2ad6: fsac_io_manager::create_manager + 0xc6 (fitter_fsac)  0x8e0ba: fsv_execute + 0x295a (fitter_fsv)  0x9283e: fsv_execute + 0x70de (fitter_fsv)  end-trace  quartus ii 32-bit version 12.0 build 263 08/02/2012 sj full version service pack installed: 2  I've searched around, and the only suggestion I found was to delete the db and incremental_db folders and re-compile. I tried that and it didn't work. Does anybody have any ideas?

You can choose which ones to install and while I'd hope that you'd get a better error message if you missed one, it's possible that this slipped through.  Cheers, Adrian
