Corruption is a messy business. You may find a utility which can sort out you flash drive but sometimes corrupt is corrupt is there is no recompense.
If you do have to start from scratch the lesson you will learn is to backup and backup again - I have copies on 5 different drives.

thank you so much for answering.. I have definitely learned that lesson now. I checked with my host like you said and there is not a backup, unfortunately. I tried to recover the flash drive with a few different methods and services, but it was hopeless..

I'm going to keep 5 copies like you after this too.. ((:

If files in folder catalog/ are corrupted, overwrite with files from original opencart 1.5.6.1 archive.
If vQmod installed, check if new theme comes with xml files. Delete them from folder vqmod/xml.
Thank you so much for answering.. I did try that and even if I select my old theme (which worked fine before) or the default theme, I still see a blank page. I do use vQmod and there is an .xml file for the theme, but there's only one.. I can do what you said about overwriting the catalog files with original opencart files and see if that works (:
and I do have new information now.. My homepage is blank, but I've found that the entire website is not. Most pages do actually appear if I navigate to them another way, other than using the main page. For example, my website is
http://www.birlirakarla.com so when I try to open that or
http://www.birlirakarla.com/index.php?route=common/home it is completely blank - but if I open
this page:
http://www.birlirakarla.com/index.php?r ... 00_101_104 or another through my chrome history - It appears almost exactly as it should, with the new theme and everything..
I went through every directory with filezilla and I've made a list of all the files that were modified in /catalog on the day/time that I installed the theme. I expected the theme installation to only change files inside the theme folder - but I'm not sure if that's right..? Many other files outside the theme folder were changed, too. I'll write the modified files in case it's helpful, and to ask about overwriting the files from an original opencart archive..
All of these files below appear modified on the date/time that I installed the theme, so.. is it okay to overwrite all of these files with the original OC files.. and then nothing else will be lost? and should all of these files be changed when installing a new theme ? thank you guys so much for answering. I really,
really appreciate your helpful answers..

Almost nothing was changed in the admin directory except for a new file added to /module, it's a new file that gives me a module in the admin area where I can customize the theme.. no other files were changed in the admin as far as I could tell.. and the admin works fine, including the theme's module.. thank you again
