HELP!
Here what problem I encountered. Normal photoshop 7.0 suddenly started to kink. When I try to run it under "initializing the memory" (when it is already the middle of the screen a rectangle with the eye) gives a window with only knopki "OK" and the following text (in my free translation): "can't start photoshop because the file is already in use or was not closed". After pressing the button "OK" photoshop completely disappears.
What to do? The method of the battery and subsequent re-installation does not help ((
System - Windows 7. Problems arose immediately after the installation of Dr. The Web, though, maybe it's just a coincidence.
Thanks in advance for your help and advice!

Hello ladies and gentlemen!) Go straight to the essence of the problem. Worked in the same .psd file, the source always remained normal and were opened too, until today, when opening, did not see that all the layers are merged, and the image is just black. The weight of the file has not changed. Is it possible now to pick up this file? Tried various utilities, but they did not help. Thank you.)
