Eleven Rack Reamp

[JMichalski]

I recorded DI tracks, and I have a signal going to my amp. I'm using an xlr output on the back of my amp sent into the mic input of the eleven rack, however, there is no signal. What makes this confusing, is if I don't change any setting and attach a mic to the xlr, I have signal. If I disconnect the signal going into the amp and plug my instrument in instead, the mic input picks up signal. I can not send a signal from protools to my amp and get signal from the mic input at the same time. Any help would be appreciated.
