I presume you mean ricardo_tv. It looks like he's more of a repainter than original author. From the instructions in his Readme file English is not his first language. This is the only Biman
Bangladesh Airlines file by him I can find. http://simviation.com/1/search?submit=1&keywords=Boeing+777-300+Biman+Bangladesh&categoryId=
I did some detective work on the 2 sms planes air india and bimen. I checked both aircraft cfg's and its all scrambled like it was some foreign language. maybe thats the problem.
I downloaded the file to check it out & see what you mean. The Aircraft.cfg file is illegible & therefore useless. (Looks like binary code.) No aircraft can display in FS without a proper Aircraft.cfg.
I haven't checked out his other files.
