iMacros batch with sleep time

I made a few imacros files, that work pretty well, however i can only execute them manually when ie is open from the left panel with all the imacros, i'm unable to invoke them from a batch file and make them run all them one afte another.

i have another problem with this, i need to run one of the 60 seconds before all the rest (is some sort of VPN verification connecction, im not so sure what it is, but i takes like 1 minute to load and until this first macro is not fully loaded it wont let run all the others)

so i need some sort of batch like this:

run first macro.iim
wait(60 seconds)
run second macro
run third macro
etc...

theres no problem in running second/third macros in paralel as long as the first one is already fully loaded.
