ActionScript 2.0 :: XML Loading Fails 1st Time?

I have a flash file that loads 3 straight XML files, one after other.And in every single code I have the sucess condition, like this:

ActionScript Code:
if (success){
doRightStuff();[code].........

Later, I added a function and an Interval to do the verifying:

ActionScript Code:
goBack = function () {
gotoAndPlay("untilItWork1");[code]..............

Didn't work also. Las try was a completely stupid addition: a variable counter that increased it's value 100 times (doing the XML calling and loading everytime), to check if the problem was some delay issue. 5 minutes later, it didn't work also.The second time I load the f**king page, it works like a charm.
