I've had that happen to me before... Not necessarily on that addon.... But it would hang on one particular addon and never finish.... I solved that by only integrating 4-5 addons at a time. Then after it integrates and finishes, close W7 toolkit and delete the W7T folder on you main drive. Then integrate 4-5 more and repeat.... I think its a bug in the toolkit (not sure though)... It only seems to do that to me when integrating alot of addons at one time.... When I stay with just 4-5 it works perfectly... I'll be doing a live install tonight and will be integrating that particular addon, along with a few new ones I plan on releasing, so after that I'll post back to let you know how it went...
