We just installed EVO, Bare with me. In the TAS-Q Change logo, we wanted to put our company logo.  
 
We put in a GIF file and put it in the same file location as the EVo GIF, and now when you start EVo it says: "Invalid GIF signature"
 
I tryed to go back to TAS-Q and it wont let me back in to change it back. It says the same error wnen i click into it: "Invalid GIF signature".
 
And now the mouse arrow is now the hourglass, like its still trying to find the file.
 
What can i do?

Thank you. The quick fix was to rename the GIF file.  
 
I took the evoerp.gif and changed it to evoerp1.gif, and renamed my logo file to evoerp.gif and copied it back to the server files. Seems to have fixed it and works well. Thanks!
