Cant do in-app purchases o.0

[TobiCoyote]

Okay, so, I decided to get my credit card on Apple, so once it was configured, I Went on to Minigore and Tried to buy a pack, It said I couldnt buy it with my current account or smthing like that, so I uninstalled Appsync and tried again and no luck, I later tried in Megajump, and it somehow worked o.0 Then I went to Infinity Blade, and It didnt work -.- How to... Fix this?
BTW Do they accept Purchases Worldwide or only US(I mean Infinity Blade and Minigore)? Cuz Im living in Mexico now, but I have my iDevice in ENG and all.

OMG Forget it... I went into Cydia to reinstall appsync, and I noticed it was still fkin installed!!!!!!!! Grr... Anyways how can I remove the following error: /VAR/Cache/apt/archives/com.skrewcommon_1.60-7_iphoneos-arm.deb Trying to overwrite '/Library/MobileSubstrate/DynamicLibraries/zRingtonesHook.dylib', which is also in package com.xsellize.skrewcommon
How to?

Get rid of appsync and actually pay for the app, it always works. Sorry, you'll get no support for warez or cracked app info here.
May want to re-read the forum rules.

Oh ok, I see, thanks anyways, But either way, how can I get rid of that other error?
And BTW, I hadnt cracked this and various other apps, I actually pay Apps that are more than 80 MB in size.
Edit: Oh, I uninstalled Skrewcommon and the problem is gone, but if I install another app that includes Skrewcommon the problem may come again :/
