Marketplace settings have no effect

Hi,

I installed marketplace and it did work. I then installed some other modules which broke my site. I rolled several modules back, uninstalled them, deleted the relevant database tables etc. to fix the problems.

I am now trying to reinstall marketplace. I have moved the module to sites/all/modules, enabled this in admin/modules and ran update.php (no updates seemed to haven when doing this even though I had previously deleted all tables to do with marketplace including those entries in the system table).

I can configure settings in the admin -> store > sellers config screen. I set a minimum sell price, hide unnecessary fields, set the commission rate etc.

I have a role called seller who has permissions 'act as seller', 'create products', etc. but when a seller goes to list a product the normal product screen is visible i.e. no unnecessary fields are hidden, no guidance is visible about minimum prices and no commission rules seem to be enforced.

Finally, after installing marketplace the first time, a user was able to upload a product and this was committed as a feature. This no longer seems to work.

Please advise and thanks in advance.
