We’d need more information. As it appears to work in general, something seems to happen on either system that causes hiccups.
a) did you change anything?
b) did you try to re-connect after the hiccups came back?
c) what are the systems involved, PC/Mac, audio hardware, latency (blocksize) settings etc
d) …you know you must not activate constrain delay compensation…
e) …and that ASIO Guard should be off…
…if you read the manual 
Good luck anyways!
