Help: Quartus II Internal Error: Sub-system: QGQ - no Change Manager Window

I am using Quartus II 64 Bit Version 13.0. I run a project while I was running the same project in Quartus II 64 Bit Version 8.0.
I did that because I have just installed the Version 13.0 and I am not familiar with it. The problem is that unfortunately the quartus Version 13.0 presented this error
<internal_error>
<executable>quartus_map.exe</executable>
<sub_system>MEM</sub_system>
<error>*** Fatal Error: Out of memory in module quartus_map.exe (14183 megabytes used)</error>

<version>Version 13.0.0 Build 156 04/24/2013 SJ Web Edition</version>
</internal_error>

Then, I closed the Version 13.0 and I continued only with the Version 8.0.
Now, I tried to open the Quartus II 64 Bit Version 13.0 and it showed this error:
Internal Error: Sub-system: QGQ, File: /quartus/sys/qgq/qgq_main_window.cpp, Line: 288

Quartus II 64-Bit Version 13.0.0 Build 156 04/24/2013 SJ Web Edition

I have to say that I have not the Version 8.0 open as I had closed it. Moreover, I uninstalled the Version 13 and reinstalled it again but the problem has not disappeared.
Please help me. What is the problem and I cannot open it?
