admin interface crash when installing extension

I was attempting to install the square payment module to my version 2.2.0.0. I got the green bar saying that it had installed successfully but I got a block when I tried to hit the continue button. Like a dope I went to the modifications and refreshed. Now I have a blank admin screen. I found out too late that I ran out of allocated disk space during the installation. Woulda coulda shoulda.

I went to store>>error_log but the file date is 7/27/16 and I see no entries since then.

Is there some other place I can look or can anybody advise me what I should do next? I checked the store and all of the data is still there. Thank you in advance.

1. Increase your free disk space.
2. Uninstall the extension.
3. Re-install the extension.

If I uninstall the extension, will all of my product data be lost?
