Here are the commands including Robert Israel's suggestion, and starting from eq in his post above, I didn't copy it here,

eq1:=convert(eq,FirstKind);
eq2:=eval(eq1[1],[f=1,c=0]);
dsolve(eq2);

But again, as Robert Israel said above, Maple won't give a general solution, because it doesn't exist for some particular choices of constants.

lasterror might come from some old worksheets.

By the way, I often have various problems with debugging of old worksheets. The problems mentioned there are still not fixed - 2 years since then.

In first message, nothing is said about i being positive - instead, the positivity of j is repeated twice. Also, k disappeared in the formula with Maple notation, so it is not clear how to interpret the statement about it in the first message.

It seems as if something is wrong with lasterror processing inside try ... catch. Replacing lasterror with StringTools:-FormatMessage(lastexception[2..-1]) seems to be working OK.

I changed your I to J and Sum to sum,

eval(J,[i=1,j=1,mu=-1]);

   -2 hypergeom([-1, 1/2], [-2, -1/2], -1) - hypergeom([], [], -1)

evalf(%);
                             -3.367879441

It's not that simplify doesn't work - it works the same. The problem is in using %.

Sorry to hear that. In Linux, Classic interface is not that great. Anyway, it can be started from terminal as

xmaple -cw &

or, if you have more than one Maple installed,

/usr/local/maple11/bin/xmaple -cw &

Click Start button in the left bottom corner of the monitor, then All Programs, Maple 12, Classic Worksheet Maple 12. If you use it often, you can drag this link to the desktop.

For many people it is the standard interface.

You could, perhaps, use profiling, see ?profile and ?exprofile to find where leaks come from.
