I have latest forge installed, but i did redownload/install it to make sure....with same results. Using optifine/gl shaders. Kinda odd since logisticpipes works ok and they are forge 1.3.1. Is there a workaround to skip the versioncheck?

Will do and let ya know. Thank you

Edit: Yep that did the trick...some work but well worth it =) Got that redpower id-conflict also, had to change array.id and machinepanel.id to 193 and 192 and setup above is running smoothly now.
