It cannot tell you that it's version 3.3 because I never released a version with that information (ProfitUI 3.3 would still tell you that it's 3.2
).
Thanks for posting the /tree, that looks ok so far, maybe deleting the \Cache folder helps and doing a clean install without additional mods (e.g. POIfinder). I had asked for a /tree from the root level however because I wanted to make sure that there is no other installation lurking somewhere. I did double-check the files and I can assure you that there is no reference to
eq2ui_newcharscene.xml anywhere.
In case ProfitUI 3.2 helps and you don't have it anymore please see attached.
The only windows that I could imagine causing trouble in 3.3 would be the browser window and may the Japanese stuff. Try deleting
_ProfitUI_Styles.xml,
eq2ui_inventory_market.xml and
eq2ui_mainhud_browser.xml from your ProfitUI 3.3 folder and see if the UI loads up then (some stuff will be broken because of the missing files, but you will see the graphics at least if it works).
