bmp export error

Hello,

Recently, I upgraded my Materials Studio to 6.0.

In previous version (5.5), I've had no problems in exporting the results to bitmap image (bmp) with high quality (above 2000 x 2000 pixels).

After the upgrade, I couldn't export it to bmp file with following error message.

The document could not be exported:

Failed to export document to C:\~~~~~~~

- Internal Error

The results could only be exported with dimensions of below 512 pixel in height, after many tries.

I don't know where the problem is.

Please let me know the solutions.

Thanks

Minsari
