Half hour compiling after upgrade?

i upgraded to 3.4.0 beta 1.. and a project i exported to android .apk before is now hanging on compile.. do i have to change the keystore?
at a half hour i stopped it and tried again... and its still going.. another 10 min.. any way to see why its still compiling.. i see the log viewer and its still doing things.. i dont think it ever took this long before even though i am running 4gb ram

Every time you upgrade Stencyl, all the engine and library code needs to be recompiled. Subsequent compiles should be faster.

I usually open the log window, so I have something to look at while waiting...

ahh. okay.. and it eventually compiled! makes sense... and my crumby laptop doesnt help either haha
