Problem with enabling Crossfire mod in Flmm

hi i am a new player
1.installed clean 1.0 game
2.installed flmm 1.3 on it
3.installed crossfire 2.0

after 3 trys a was able to aktive crossfire in flmm and start game in SP and MP (had errors while converting)
in game saw issues with widescreen so i deactivated the mod and wanted to aktive with widescreen
since then i always getting this error while converting in FLMM

Error: problem activating 'Crossfire Mod 2.0 Client Edition'
Error: SHCopyFile failed ('D:\Freelancer Crossfire\EXE\resources.dll.flmmbak' to 'D:\Freelancer Crossfire\EXE\_resources.dll')

i deinstalled and installed again using this link
https://swat-portal.com/forum/index.php/wcf/faq/#faqEntry-18

still getting the same error while converting to crossfire
has anyone a idea what should i do or not to do?

fixed it installed 3rd time and worked

i dont know what the problem was
i installed the game with mod twice and got this massage in FLMM
Error: problem activating 'Crossfire Mod 2.0 Client Edition'Error: SHCopyFile failed ('D:\Freelancer Crossfire\EXE\resources.dll.flmmbak' to 'D:\Freelancer Crossfire\EXE\_resources.dll')
while waiting in forum for answer i deinstalled/installed game again-the third time
aktivated CF in FLMM instantly(the 2 installations before i always waited few minutes till i got the error)
thats all i know
