How to Resolve - all OTFs (PFM and PFB too) "not a valid font file" after recent maintenance reboot?

all OTFs (PFM and PFB too) "not a valid font file" after recent maintenance reboot

Few facts:
 
When accessing fonts in Extensis Fusion 2 - all fonts except for TTFs displayed as "font unavailable"
Effected fonts are not both fonts I have installed but fonts that came with windows 7
Double clicking a OTF file doesn't open the FontVeiwer but "The requested file c:/...XXX.otf is not a valid font file."
 
I have:
 
Restored to a date previous to the reboot
uninstalled Fusion 2, checked fonts - issue remained
reinstalled - issue remained
 
Per research I have made the following change to the registry: HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/SessionManager/MemoryManagement
 
Add a new DWORD named SessionImageSize and set to decimal value 20, reboot.
Issue remained
 
Per research I checked my graphics card's drivers.
I do not have either of the graphic cards that caused issues and my drivers were up to date.
 
 I plan to:
start in safemode and see if there is a diff.
My computer:
HP p6367c
Intel Core2 QuadCPU Q8300 @2.50 GHz
8gb
64-bit operating system
 
 
I am a graphic designer and this is quite crucial to my work! I am not very tech savvy, just enough to get by.
I am not sure what else I should provide.
 
 
I greatly appreciate ANY help!
 
 
Thanks!

Hello ncarter11,
You might try to do an in-place upgrade or repair before attempting a factory restore.
However, you will need the installation DVD to do the repair.
The In-place Upgrade will not affect settings like photos, movies, documents, etc.
that are saved on the computer.
Though this operation will not remove or modify the installed programs and files, I still suggest you backup the important files before
doing this.
In addition, you may have to reinstall the device drivers after this operation.
The detail steps are included as below:
In-place upgrade
====================
1.
Log on the system first.

2.
Insert the Windows 7 DVD in the computer's DVD drive.

3.
Click Start and choose Computer.
4.
Find the "setup.exe" file in the DVD-ROM and double click it.
 
5.
Click Install now.
6.
When you are prompted to input the product key, please click Next directly without inputting any key.
The setup wizard will prompt and asking if you confirm to install Windows Vista without the key and please choose to confirm.
7.
When you reach the "Which type of installation do you want" screen, click Upgrade to upgrade the system files of Windows 7.
 
Note: While performing the in-place upgrade, the system will restart automatically (Several times) to merge the files and programs, please leave the computer alone and do not configure it until the "in-place upgrade" completed.
The system will start Windows
7 once it is upgraded.
Once the computer is performing "in-place upgrade", you can go away and leave the computer and it will complete automatically.
If you cannot do a in-place upgrade, then I believe your other option would be to do the factory restore and see if you can get your fonts back.
 
Please reply back and let us know.
 
Thanks,
