I had the same problem.
For LFMN the problem is that runways in the FSB_SIDS.txt file are 04L, 04R, 22L and 22R.
In the Fsb_apts.txt file, LFMN runways are 05L, 05R, 23L and 23R.
I think the runways numbers have changed and the Fsb_apts.txt file has not been updated.
According to the official french airport site, the runways for LFMN are 04 and 22 :
If you replace the line beginning by LFMN in your Fsb_apts.txt file by this one it should be Ok :
LFMN COTE_D_AZUR 13 N43:39:37 E07:13:03 04L_9679_N43:39:00_E07:12:24_045_--- 04R_9712_N43:39:00_E07:12:24_056_--- 22L_9712_N43:40:00_E07:13:79_236_--- 22R_9679_N43:40:00_E07:13:83_225_---
For LSGG the problem is that the SIDs refers to the runways numbers without L or R.
If you add the L and R in the FSB_SIDS.txt file it should work.
Open this file, search for [LSGG] and in the lines below, replace the 05 at the end of lines by 05L,05R and the 23 by 23L,23R
For example the first line after [LSGG] will be :
T ARBO1P ARBO1P 05L,05R
Ernie : you said the SID were in your FS Build. Maybe you didn't put your last files in the update package ?
I downloaded the update from fsbuild.com and the date of the files that are not correct are :
fsb_apts.txt 08/29/2006 06:44pm
fsb_sids.txt 08/28/2006 09:21pm
Hope it helps.
