[TUTORIAL] 27.7.X2 AS3 Client to FSOD

so i've done everything you guys have suggested, and i either get the same error as before or i get this new one
Error59, 30) [WebMain]: Error code: 1017: The definition of base class Sprite was not found.
i've used flex AIR, 4.1, 4.14, 4.15, 4.60, and 4.9.1.. i have Intellij Ultimate.
so if you can think of anything else i'm doing wrong? thanks guys!!

so i got flex skd 3.6a and im getting this error

Error:[WebMain]: command line: unknown configuration variable 'swf-version'

- - - Updated - - -

so i haven't tried flex 4.14 my bad i cant find a download leink, all the sites are servers are down for that version or something

I have done everything on this fucking tutorial like 4 times, and it just keeps giving me a 3kb file named "WebMain", and if it doesn't do that, then the client I arrive at just still connects to only actual rotmg...Please can someone just tell me what to do or link me to a as3 client that I can edit the IP in yogda? this shit is ridiculous honestly

I get the "1017: The definition of base class Sprite was not found" whenever i try to rebuild with both 4.9.1 and 4.14.1 in intellij.. I'm pretty sure I did all the steps correctly, and i replaced the realmofthemadgod url with my ip (i put localhost : port) this is like the 3rd time i'm trying to get it to work

You remove all friend files and then you'll get some errors and then u fix those errors then rebuild then you'll see that the friend icon is no longer in existence

the errors should be ez to fix, you just have to remove some coding in a few different file thats all

I'm getting an error when I start the client which says "D'oh this isn't good" "An error has occured: Unable to load language [en]"
Please help me. I really want this to work. thanks
