SDB is the Smart Device Bridge and it is what connects the computer to your watch.
Do you have all the proper Samsung Author and Distributor Certificates? Do you have debugging enabled on the watch? did you accept the RSA encryption key. Do you have Developer Options enabled.
What kind of App is this? Any other information can help track down this.

If you don’t then we can look more into possible issues.
