Recently downloaded the 1.7.10 modpack Hypovolemia via Curse. Ran into an issue with BiomeTweaker that was recommended I bring to your attention: Ref: MyM-ModpackTeam/hypovolemia#162

Besides several shortcomings in the script...

[11:17:56] [Client thread/ERROR] [SuperScript/BiomeTweaker]: Object not found: import pizzaluc
[11:17:56] [Client thread/ERROR] [SuperScript/BiomeTweaker]: Object not found: import pizzaluc
[11:17:56] [Client thread/ERROR] [SuperScript/BiomeTweaker]: Object not found: import mods
[11:17:56] [Client thread/ERROR] [BiomeTweaker/BiomeTweaker]: Failed to find meaning in command remove(21,  6, 2). It will be ignored.

Your error is caused by a lack of permissions. BiomeTweaker does not have permission to write it's output files

Caused by: java.io.IOException: Access is denied

That's a -you- problem.

I've disabled the UAC and ran everything as administrator on an admin account, yet the issue persists. Any recommendations on who to contact to try and resolve this?

Seems I missed a single executable in java. Once I set that to run as administrator, the issue was resolved. Still weird that i had to do that for Hypovolemia but not Regrowth.
