I'm sorry to say this, but a bug was found in The Add-on Handler. It involves installing buyable skins. Thanks to Kerry (Tech Mod at Neighborhood 99), I now know TAOH installs buyable skins to the wrong folder. This bug can cause problems when duplicate meshes are installed (one copy in the regular Sims folder, the other copy in the SkinsBuy folder), as it'll crash the game. This problem was reported only shortly ago, so I haven't yet been able to fix the problem. However, I will solve it very soon, and you can expect a new version very soon (within the next few days). That version won't have any new features yet, but it'll just have this bug fixed. Until then I recommend not to install any buyable skins (deselect them in the window you get after dragging the files to TAOH, by double-clicking the following group(s) in Skins/Meshes: Formal Wear, Nightwear, Swimsuits, Winterwear). I apologise for this inconvenience. I've temporarily taken TAOH offline until the problem is fixed. I expect to have the new version ready within 48 hours.
