Upgrading JDownloads 3.5.1 to 3.5.2.

Hi Tom,
versions like this exist not. Please check it again.

[Arno]

You can try this:
- download the newest version 3.2.52
- unzip it on your PC
- open this file: /admin/sql/updates/mysql/3.2.9.sql
- make this file empty (remove every text) and save it
- go back to the first folder com_jdownloads and zip it again
- try again to install it

Just use the file below.

Which is really your old version?

Edit:
maybe it would be easier when you send me login data for your backend via PM.

Thanks for the login data. I hope I can check this at the weekend.
