I solved the problem thanks in advance

Hello forum members! I have had a terrible accident. A long story short. I have been working on a webshop for about a year towards a launch that is supposed to be tomorrow 4/4-2014. Whilst working on the final parts and getting these done. I stupidly decided to try an upgrade. I did a backup of the site before starting the one-click upgrade just in case. When the upgrade was done, I noticed that the layout was different and totally corrupt, so I had to do a rollback. So I did a rollback to the backup I created...Sadly It did not work because of some frekking Readme.txt belonging to my shipping module that did not get removed. If I don't get this sorted out by tomorrow I will probably get fired. I am most grateful for all the help I may receive. I have included a screenshot. Now I am unable to even log in at all. All pages returns a 403 forbidden. Hope there is someone out there that is able to save my night Kind regards Leonard
