Answer

Hello James， 
The following sentence is not translated precisely:
好久没有受到你的信了。
Hao jiu mei you shou dao nide xin le .
" hao jiu " means 'quite a while' .
So the correct translation could be:
"I haven't received a letter (from you) since quite a while"
"It has been long （quite a while) since I received a letter from you."

Answer

Hi! 
It's a good translation. 
There's only one small thing I want to notify. 
Wo xia ge yue ba hao zuoyou yao qu Guangzhou kai hui. 
(ba hao zuo you) usually means around 8th. I am not sure whether it is correct to use around. But I mean, it could be on 7th or 9th as well. The writer himself is not sure of the date neither.
