well... may have spoke prematurely. did a little prunning of my collection and went to 'resync' with match. Seems to be doing the same thing all over again, stuck at sending information to Apple. After adding two new songs. really think something is a miss with the iMatch service itself. And yes, I've tired all the normal workarounds, and them some.
1. Turning Match on/off = stalls at step 1
2. Signing out, turning off match = stalls at step 1
3. Deauthroize computer, turning off/on match = stalls at step 1
4. Restarting computer = stalls at step 1
5. Restore iMac computer to factory setting = stalls at step 1 (Only Apple software, no virus/firewall, etc.)
6. Plugged directly into my cable modem bypassing home wireless router = stalls at step 1
7. Stopping/Starting itunes match = stalls at step 1
8. Built a VM with 10.9.3 Beta and iTunes 11.1.6 Beta = stalls at step 1
9. Built new libary = stalls at step 1
10. Tired 23 different lib. backups from time machine which I know worked with iMatch prior to May 1st = stalls at step 1 with each one of the 23 libs.
11. Tired iMatch from MacBook Pro = Added new song to iTunes = stalls at step 1
12. Tired from Windows 7 Laptop = Added 1 new song = stalls at step 1
13. Tired from Windows 8.1 VM = Added 1 new song = stalls at step 1
14. Disabled iMatch on all devices and re-enabled only ony my iMac = stalls at step 1
