First off what tracker are you trying to get BiglyBT to work on?
Secondly, check whether you have the modded version. Have you followed the coder's instructions to get the modded version of BiglyBT?
Thirdly, share screenshots of your settings you have chosen to use. Also include affected torrents, http responses of affected torrents from the tracker.
As said before please be more brief on the subject also share screenshots and make sure to protect your identity.
There are various different settings you can use. Read through this link to understand them all:- http://www.sb-innovation.de/showthre...threadid=13781
If for some reason BiglyBT doesn't work or something similar on these lines you need to specifically point out what it is.
