open from older versions

hi

I have a score made in Nightly R3272.

I recently downloaded the latest R 3397, but my score does not open correctly.

I looks as if the score opens 9 times in the same screen (but in fact it only opens once) (screendump enclosed)

Some chords are not shown correctly, there is a square instead of chord symbols.

( and when Musescore opens the usual DEMO screen is empty)

and worse .. more often that not musescore crashes within the first 15 seconds.

I am back now in R 3272 and everything work fine.

I enclose the score so you can check if you get the same result.

regards
