I have a tenth level paladin I'd like to take through the game one more time...but the xp cap remover doesn't seem to work with the Original Saga plus TotSC (which I updated to a while back, from an older "Original Saga" version sans the expansion)...now, the XPcap remover worked fine before, but now, I just can't seem to import/export my higher level stats...can I fix this, or do I just have to grin and bear it, and start a different game?

Well you could use Gatekeeper to boost your stats and level back up.

That'll only work if the XP cap remover does indeed still work...and just to check, I used the CLUA console before I checked Gatekeeper, and it doesn't work, so I strongly doubt Gatekeeper will...
